TL;DW for the changes I would make. My reasoning for these changes and what I would like to see pvp be like are in the video.
Scoundrel:
- flat damage nerf (pve but only apply to damage against players)
- active cards expire if not used fast enough (maybe pve if you made it last like 2-3 seconds)
Mage:
- flat damage nerf (pve but only apply to damage against players)
- reduce spell lifetime
Paladin:
- hp nerf (outside battlegrounds take more damage from players)
- can be stunned to prevent hammer throw(pve too which would only affect overword pvp)
Warrior:
- can be stunned to prevent sword rush(pve too which would only affect overword pvp)
- make shield block damage of all types(pve too)
- make bleed on wound talent stack bleeds(pve too)
Musket:
- allow either killing own turret or enemy killing turret to activate speedy talent(pve too)
Shaman:
- stun orb prevents stamina regen for stun duration(pve too which would only affect overworld pvp)
- orbs immediately spawn on totem drop(pve too)
