Bro. If you want to change spar start first with spike lags and server delay. There is alot of players thats getting their game freezed at really bad moments. And its not phone problem. My phone can take chems, burners and etc without problems. But the game is still freezing every 15 seconds.
Server delay is really bad too. Im playing from russia and i see that most of my bullets dont do any dmg because im not seeing their TRUE way of flying. Thats not a really big problem, but i cant spar normally with it.
Im begging you to do something with these things before upgrading spar. Because it would be meaningless, if we got new spar and cant even do smooth pvp there.
