Tanking in FF14 question

[Curisu]

Every few levels you will get more skills added to your rotation.
What now is a simple 1-2-3 rotation becomes later something like: 123 124 555 113 77778....
In between you have to use ogcd buffs, defensive cooldowns and play mechanics of a fight while watching your team for a potential save with your heal.

So the boss fights and raids are the interesting mechanics of this game, not the dungeons.

Aoes are kinda lame for the most classes, but they just made it a bit more enjoyable in the current expansion.
