i find i rage more on EU seige than NA seige, mostly because of the stupid ass range spam and teamhits. EU seige is a lot dumber in peak hours imo
Imo there is more tactics on Eu than NA, hell yeah there is more ranged, it's a siege...
Only tactic i saw on NA is go go go go, only using one way for attackers, defenders fighting always on walls and forgot about the flag, i rage much on NA because my teammate are dumb and didn't understand the meaning of siege (i don't even speak of defenders trying to attack attackers outside the wall, hey guyss you can't take the flag, it's not strat!).
About teamhit, teamkill, it's the same on every servers, don't try to search for kills qhen 3 of your teammate are already on one enemy, if the guy is smart he can make hit each others with some footwork.
