When I play any of the battle modes, ı can not fire, move and rotate my turret in the same time (but other players can) so I can not play very well with turrets such as firebird, freeze and isida.
It could be that your keyboard is ''Ghosting'', you can try change key bind for some keys in Settings, other than that there is no other soution than buying other keyboard.
You can read about Ghosting in here.
Thank you for your suggestion. I tried it and it worked! Also I'm very happy now; I couldn't play like this more than one year. :)
