Buffing EFA to WFA is a bad idea. The longer the infantry fights are the more tactical and less RNG they become. It is the WFA that need to toned down.
I was originally all for this idea btw.
The problem is that if you take all infantry and scale it back, you would have to rework tank vs. infantry dps, and much more importantly, close quarters infantry would always beat the snot out of long range infantry. This is because if they all go at the same speed but all do less dps, the cqb troops will have a much easier time closing to < 10 meters, and would take less damage in the process, basically making it so that cqb troops always have the advantage. With the current efa cqb troops this isn't so much of a problem since they consist of shocks, assgrens, pios, and pgrens, all of which except pgrens aren't that great and pgrens are a weird mid/close squishy squad so they kinda don't even count. Also, grenades would be op as shit for the same reason. You could just break cover, chuck a nade, and run back to safety and be way less punished than with the current overall damage model. That's just my opinion anyway.
