It was way more unbalanced during HW. Same toolset in PvE and PvP plus some additional PvP exclusive actions. It was a freaking nightmare on console/controller. No separate hotbars either.
Now PvE and PvP are completely separate which means they can do adjustments for one side without affecting the other.
Some people (and their friends) will leave and stop playing but they will be replaced with new people that started playing with 4.0 and later.
