Pvp maintenance was totally abandoned.
There is too much to fix. Pvp times are over.

But if u wanna try....
First of all a general rebalance a huge fix for all class biggest problems are.
Too high armor and healt value on tanks that make them near unkillable.
Too high damage provided by daggers, daggers should have high attack speed not damage. Now they have best damage and damage for second.
Too much ping on pvp, too much spikes if u play a speed set game its totally garbage.
Waste of mana by mages, because u didn't go under 75 % of it always in fights.
A real new mechanic based on mana is needed maybe mages will come back.
And too light mana consumption and regeneration of other 2 class. Now u can easily play without a mage and have always mana bar full.
Armor values in low lvls.
Apply some reductions filters % on low levels for twinkers, because pvp from lv 0 to 40 is absolutely. Damage output is very low and armor values are just crazy.
Hope this will help
