Hello mate,
You're talking about US servers I guess ?
Got to try about 5-6x games online yesterday night and it was HORRIBLE. Moving players is quite bad but the worst is the input lag.
Had no real problems with 2015 on my side (yes offline was still better, but had no big input lag whatsoever)... maybe the servers load for the launch ?
The biggest issue is the impossibility of playing full manual : one-touch passes are totally impossible.
The power jauge is always at minimum, no matter how long you press X. So basically the pass just leave player's feet a bit and that's it.
The power jauge problem is the same with assisted settings but as the game compensate for the power, it's not really noticeable.
Too bad also lvl 1 is WAY too assisted but hey, that's another topic...
On a side note I can't BELIEVE there's still no match making per team strenght... it's again endless Real / bayern matches in divisions...
