The whole "battle communication" shit is finally gone. Nothing was worse than being super sure about your hits and let it all be handled by a system that's completely random. This was one of the things that really put me off from FH2 because tanking and tank hunting was what I enjoyed doing since I have always been and will always remain crap-extraordinaire at infantry combat. Now I might actually get back to it.
As log as we don't go back to the "tanks made out of paper" situation like in pre 2.4 I'm fine with it. Maybe infantry will need some kind of (slight) nerf, since they had their (in)visibility buffed with the new shaders and also effectiveness buffed by unlimited sprint time (or some maps will need to be a bit rebalanced regarding availability of AT kits). I guess time will tell.
On the other hand wrench has no cooldown anymore, so an effective tanker crew can still put up a fight (but those are hard to find)
So since we're already at "fixing old things" when will we get suppression fixed? I'd love to see some actual firefights instead of the old lazer-insta-gib-Unreal-Tournament Fest (although, to be fair, things did improve with the latest addition of graphical sway, at least on longer ranges)...
