It's actually not simple at all, otherwise the Maxim wouldn't have been changed so many times to the point it doesn't even resemble the MG that it was at launch. You can't say something is simple when it's literally been debated since the game was launched by everyone
And "faction quirk" is not a valid argument against what I'm saying. I'm not saying the Maxim should even be as good as mg42. It just shouldn't be this bad while costing the same and requiring fuel to unlock. It makes no sense
It is SIMPLE, some people like to complicate things.
Let me enligten you a bit.
(unit type) + MP + Abilities + (Faction quirks) + Time = Cost/Balance ratio
Now replace each part with the correct items.
-Type is a force multiplier. I.e. HMG has 150% efficiency stopping infantry.
-Abilities are all the abilities/upgrades
-Faction quirk is a real property
(you ignore it in this case because its about OST and you know well OST is teamweapons oriented), can sometimes be positive/null/negative.
In the case of SU it could be 6 man crew for TW at the cost of 0.75 efficiency.
-Time could be either its rushed time or its average time, those are the limits, it incluse training time of course.
That its, now you do the math while i drink my tea.
Added. Rude of me to not do it myself. We can discard the time but they can be converted into a hidden MP cost (an opportunity cost) to make the example simple enough
A maxim costs in a representative example 100MP (It costs 260 IIRC, i dont memorize sry)
HMG type (150%) + 100 MP + Maxims normal fire means no modifier + "Quirks" (75%) + Time (discarded)
Result. A maxim will reliably counter (100*1.5*1*.75) = 112 MP
It means that at most 112 MP, even being an HMG units have a power ceiling
