The issue is as follows:
You don't know if you get the kill other than a "plink" sound which could also be ammo empty.
Snipers everywhere on large open maps. A game earlier, there were nearly 40 snipers in a 64 man game...yes...40!
Shotguns on CQB. They were used a fair amount on amiens, and argonne forest, but now, nearly everyone uses them and you can't do anything to combat that but use shotguns.
Tanks, artillery trucks and such are way over powered now with the damage increase, but also they're tougher in terms of damage needed to beat them down.
Trains - pretty sure they've been weakened...used to be 15 anti tank mines to destroy them in the beta. It was upped to 24 on release. Back down to 18.
K bullets do LESS damage on a person than they used too, but slightly more damage on vehicles.
As for the servers...admins aren't even in their own whitelists for the server. Lack of kick and ban features. Customisation for weapons is a choice of turn kits off or keep them on. Same for vehicles etc. Needs to be done so we have something like rcon.
