Could you elaborate on your point? Because if your MG is getting suppressed it becomes a little bit more useful then useless and not like Maxim won't outsuppress even mg34. Maybe I'm missing something about the suppression mechanics, or something like that. I'm not saying that it should be the case, just curious.
The supression effect of MG crew is different, or better said the effect on the MG is different. For the exact numbers I have to look in tools. But shot: If HMG42 gets light suppression the DPS output drops because of shooting delays way more than of Maxim. Maxim will still shoot and will get some effect on the field.
That factor plus larger crew, build up/down speed and quick rotation is the reason why maxim spam is so effective.
If there wouldn't be bad crew placing and death-loop the unfair mechanics would be not counter-able.
For me something that can be fixed by some handy-caps. Give Maxim its old angle back, but add a defensive mode to increase the angle to HMGs 42 level but lock it down for some sec. So Maxim needs more micro.
