?? Of Course a WELL timed rifle nade will have effect. Thats the point behind well timed. Did i mention well timed ones or the General use? Look it up before u tryhard with your passive flamin'.
What the hell is a "general use" and "a well timed grenade" You made no distinction in your post, and any "general use" greande must be well timed or it will obviously be dodged. But this still doesn't change that rifle nades are the best nades in the game and are of course also require no research.
Like seriously, buffing grens is the last thing this game needs right now. Nerf allied infantry if you want, but do not buff grens.
Oh and btw you dont need to rely on grens vs USF or UKF. Snipers have always been the counter to them, and that didin't change.
I'm not even talking about the insane combination of command tank + LMG gren blob making your LMG blob essentially unstopabble or CAS which allows you to easily outspam your opponent by making a huge LMG blob after 3CPs.
I don't see the problem of rifles or IS outscaling grens. IS are a bit too cheap for 28mp though.
