Overview

Often seen as essentially being IDW 2.0, M500 is a Shotgun who seems to be designed around being used in a 2SG Echelon.

M500’s tanking capabilities are mediocre at best. Although she has an above average HP stat, her Armor -- the most important stat to an SG -- is below average, clocking in at 21. So while she can be used on her own as a tank, she’s outperformed by other SGs who excel at solo tanking. Another problem with using M500 by herself is her buff tile orientation. Although her 18% Damage tile buff is potent, her tiles are placed in a way that she buffs from the corner, not the center. Therefore, if she is used by herself as the centermost tank, one of her tiles go to waste. For these reason, she’s best used in a 2SG Echelon, which unto itself has a few inefficiencies when compared to its 1SG counterpart. That isn’t to say that M500 is unusable, though -- she’s good, not great, which is similar to many other T-Dolls in her class.

Strengths

Powerful Buff Tile

M500 provides an 18% Damage buff to MGs in her tiles, which is tied with M37 for being one of the more potent Damage buffs provided by an SG.

Above average HP

M500 has 264 HP per Dummy at lv 100, which puts her HP above the average value for a SG.

Weaknesses

Mediocre Armor

M500 only has 21 Armor, which is below average for Shotguns -- though it still allows her to perform adequately in most situations.

Awkward Tile Orientation

M500 buffs from the topmost corner. If she was used by herself as the Echelon’s main tank she’d only buff one SG, meaning that she should probably be used with another SG for buff coverage.

Full Analysis

M500, although decent overall, only shows her full potential in 2SG Echelons. Due to the inefficiencies inherent in this type of Echelon (why use two tanks when you can use one?) this does affect her effectiveness somewhat, though it by no means makes her bad.

M500’s defensive capabilities are on the lacking side. Her Armor stat rests at 21, which would be great on an offensively geared SG, but on a defensive one… not so much. Due to the manner total damage dealt is calculated, even one point of Armor matters, especially against Tier 2 enemies who carry higher Damage stats. That isn’t to say that M500 is useless, though -- she does have an above average HP stat resting at 264 per Dummy. Because of the strengths inherent to her class, M500 can tank fairly well by herself even with these stats, but because there are other SGs that perform better as single tanks it is not recommended to do so.

Another reason M500 is suited for 2SG Echelon is because of her tile formation. M500 provides a great buff to MGs, boosting their Damage by 18%. M500, however, buffs from the top-right corner of the formation, buffing a tile behind her and diagonal from her. Because of this, the only situation that results in the ideal distribution of her powerful buff is using her in the top right corner. If she is used in the top right corner, however, she cannot pull aggro from enemies coming from the opposite side of the field and another SG must be used to cover for her.

This raises the question: what’s wrong with using a 2SG Echelon? The answer comes down to whether one values maximum possible efficiency, even if that efficiency isn’t strictly necessary. Due to needing one more SG, a 2SG Echelon must exclude an HG or MG when compared to a 1SG Echelon leading to overall loss in DPS. As MGs are strong enough to begin with, however, unless faced with multiple enemies with high HP like Manticores the difference of including an extra HG or even an MG in an SG+MG Echelon is minimal. Another downside to running 2SG is the Resource cost. Running a 2SG 3MG will end up costing more Resources than a traditional 1SG 1HG 3MG team, while running a 2SG 1HG 2MG will make the cost approximately the same overall but still decreases the Echelon’s total damage output.

One benefit a 2SG Echelon has over 1SG Echelons, though, is the efficiency of tanking. In 1SG Echelons, one SG has to take on the burden of all the tanking that needs to be done, while in 2SG Echelons the burden is evenly distributed. As SGs are inherently good at tanking, however, and MGs KO enemies quickly, this positive quality will not make much of a difference in most situations. Overall, 2SG Echelons end up falling behind in efficiency compared to a 1SG Echelon but can still be used if necessary.

The last aspect to note about M500 is her Skill. At level 10, it increases her Armor by 60%, and although it won’t see use in most battles involving an SG+MG Echelon, it is rather effective in the rare cases when it activates.  Not only does it help compensate for M500’s low Armor, it also helps 2SG Echelons tank more effectively. Its 6 second duration, however, could be better. So although M500’s Skill itself is decent, its subpar duration and Initial Cooldown does make it less of a strength than it could be.

Overall, M500 is a decent choice to use in a 2SG echelon, thanks to her powerful tile buffs and average defensive stats. As with most SGs, she performs adequately at her job when she needs to, although her statline, buff placement, and Skill do leave a bit to be desired.

Team Options

SGs Suited For 2SG Echelons

As M500 should usually be used in the upper right corner, she needs another SG that can compliment her. Some examples are M590 and RMB-93.

HGs That Buff Accuracy/Damage

As MGs appreciate Accuracy and Damage buffs the most, HGs that can buff either of these stats are preferred. Examples are Mk23, MP-446, and SAA.

MGs - As with all SGs

M500 does not discriminate much based on tile buffs from MGs, so any decent MG will do. Because of her low Armor, however, considering an MG that can buff Armor is a good idea when employing her. Some examples are MG5, PK, and M2HB.

History/Trivia

The Mossberg Model 500 was the first in the Mossberg 500 series, a series of pump action shotguns manufactured by O.F Mossberg & Sons. The M500 was intended for use in harsh conditions, such as hunting and during combat. Therefore, it was designed to be easy to clean, along with having an interchangable barrel. Mossberg has claimed that the M500 was the only shotgun to pass the U.S. Army’s Mil-Spec 3443E test. The M500 was used in several wars by the US, from the Persian Gulf War and the Iraq War.
