We dont need a lvl cap. But removing outdated things that still are in the game and adding new features would be better.
Craft system, not even new ppl use it cause the only one usefull weapon to craft cant be crafted cause the aegis scroll doesnt drop anymore. Add new crafteable useful weapons. Maybe add new gems to craft.So pvpers wont depend on playing events to get gear if they are free to play players.
Update drops so farming vanity/gems/craft components would be a thing again and everyone who try to play the game wont quit cause its hard to get something decent.
Bring back the plat in nightly rewards, the old system.
Dont let join to pvp arena players that arent full equipped(gems/weapon/pet). All the alt farmers/cheaters put their toons without any gear in pvp. At least in that way wont be that easy to kill their alts.Or just remove kdr and make it by seasons.
Remove trade system. Only a.h should be used to prevent scam and black market which is huge atm.
