This game never been for soft people... like i explained, you can do everything you named for them to be more "comfortable" and still, they will quit for a reason or another.
Unifying servers will be a lag fest, and will force people who is used to lower pings to quit.
That phasing or i dont know what will get u load screens all the time, i think it will be like switching districts with every match it starts? With all that it implies -like spawning again, spawn car, etc.- it will be really annoying imo. That means less pop again, but maybe its just me.
