This will solve most of the PVP issues.

there is not issue PVE is not PVP that's all,
i don't want to see tank to force players to attack them, we aren't in PVE...
Players have to attack the enemy they want not to be forced to attack tank until he is die
i think a little cc to force player to attack them for some times made with provoke would be nice maybe^^, i am open to CC but not
too much pve mechanics in our pvp, drone is already enough...

And for caster : i play 90 pourcent of the times whm, and what deelo said is right
