On serious note. Return mana regen back to normal and increase dampenings stacking and amount instead.
In battle grounds mana regen stays normal , capture the flag games already have a built in penalty and timer. Games with resources will produce a win by default if each team owns 1 node in eots. 10 people with a maledict will get the job done on a target anyway.
Create a smarter system to populate players. Like old Half-Life team fortress admins. Allow x amount of dps and x amount of healers and a tank if needed.
Get rid of epic bgs…its a chore. Especially when you cycle tarren mill vs darkshore.
Azerite traits in pvp are like legion weapons fine. Deny use of pve gear in pvp. Conquest weapon is the first item anyway Bring back honor vendors. Your world of Warcraft version of counter strikes honor system with obnoxious and useless fluff items is embarrassing.
Get rid of macros and add-ons across all forms of gameplay pve and pvp. It will increase the skill of players exponentially. (Maybe not maybe a bad idea I dunno)
Finally do the one thing the player base has been begging since you created this game. Tune up…not down. You do create a vacuum of adaptation but you sacrifice other classes.
