I don't know if there exist any crowdcontrol(CC) class in FF.
I but as FFXIV is a PvE game I think it could have a CC class.
A class that is focused on controlling the enemy would be a greate fun to play.
This could be done i lots of diffrent ways: physical controll or mind controll.
It could be tide to elements like wind and ice.
It could be done with net and webb.
So the grafic could look realy diffrent depending on what fit's FF.
The effects of CC can be realy varied:
single target; multi target; tied to the ground.
Works as long as you don't hit them; work even if you damage them;
Gives bonus on attack for the poeple that atack them (or no bonus)
Make targets unable to move, but can still use ranged attack (or total imoble)
Just naming some of the possible variations.
