Just a little suggestion since every lvl 30 is gathering a load of xp points without any use for them, so what if the game gave some rewards for like every 50k xp or so after level 30 has been reached ? It could be anything like free item box or maybe some premium time or whatever, it would be nice

suggested this before and I totally agree xp is useless after level 30

Agree xp should be rewarded at all time, think it must be appreciated people play a lot and/or keep playing this game. It can be in credits, but rather in non buyable things like colour kits if free tokens would be to much asked!
