The rotation are always the same for each class. I would love to see a change in the skill tree system.
It would be interesting if SE could add the role actions element into the job skills where player can only pick a certain ultimate skills into battle
so player could customize their rotation and change the play style from time to time.
You could say something like diablo 3 or maybe like Heroes of the storm where player can pick only
one of the 2 ultimate at level 10 and traits are customizable.
For example:
1. SMN: summon/Dots build
2. MCH: turrets/gun build
3. BRD: bow/support build
etc. etc.
