After lurking in the bg forums I've made a list of fixes that blizzard needs to address.
-Remove gear
-Disc priests
-Twinks
-Horde / alliance populations
-Shaman ( who plays them anyways)
-Remove old players
-Remove premade arena comps
-Remove join as group
-Disc priests
-Stealth
-Stuns
-Remove interrupts
-Racials
-Xp on/off npc's
-Xp gains
-Leveling in pvp
-Honor gains
-Rating
-Doomkins
-Self healing ( of any kind)
-All gear should be changed to cosmetic care bear costumes
-All damage should be done only by a full channel from a rainbow generator
-Gear and rainbow generator should be gifted to all new toons at level 1
-Pvp level brackets
-Disc priests
-Pvp objectives ( who goes for those anyways)
-Azerite traits
-Remove rogues
-Diminishing returns
Pretty sure I got it all covered. This should balance not just pvp but all aspects of the game . Feel free to add to this list.
