And your thoughts about its cost. Does its cost properly reflect its performance?
Well, IMO the cost is not a reflection of performance only. Like real economics, costs have a lot of intended and unintended consquences. In order to keep my density at a minimun i will lay down a list of " worthy units stats™ " that are simple yet coherent aspects of the unit, relative to other similar units. They are all based on my experience but include the forums overall view (hopefully).
5 points mean ideal - 1 its awful.
Tech tree: 4/5 {Mg42 and vickers are 5 because its T0} (T2 cons build is viable now)
Damage Output: 3/5 {Vickers is 5, .50 cal is 4}
Time to suppress: 3/5 at vet0 (Vet1 enhances it, its the thread OP) {Mg42 is 5}
Firing arc: 3/5 (There are worse, but its bad anyways, very focalized)
survivability vs inf: 2/5 (i cant put it 1 because of 6 man crews, but yes, deathloop)
survivability vs AoE: 6/6 (6 man crews)
garrisoned power: 4/5 (can fight off Mg42s in garrison) {vickers is 5}
set up/tear down time: 3/5 {mg42 is 2}
*BONUS PERKS (only for SU maxims)
-Can have conscripts merge to it to avoid reposition it (its situational, but its there)
-Only SU can make it worth at vet0 (other factions are reluctant to steal it)
*CONSIDERABLE CONS
-Its literally the worst HMG SU can have. (But Dshka and stealing is still an option)
-Deathloop (it is really an offensive overflow, other factions cheat having teleportin MG)
Final veredict. If you only pay for suppression its a bad HMG. SU faction perk its the true positive side of maxim. But at least you can have maxims in a reasonably early time. USF cant have this luxury and thir HMG is 4 man. OST relies on 251 to keep HMGs and TW online. it is a FU dependent solution, merge is underrated and costs MP + micro, M5 can do as 251 if needed. Maxims are relatively as pricey as Mg42 but trades better and can survive longer if managed well. Merge is underrated but also clunky AF, could use some love.
It is not a lategame HMG though, but SU have other units cover that area very well, from DshKa to rocket arty.
