Combat Gameplay - Ninja

[Alberel]

So, ninja DOES have combos. And judging by the presses seen at 0:21- the mudras are instant, off global cooldown and use a trigger ability to end the chain.
Once the trigger ability is used, that and all the mudras go on cooldown

Given the way it works I'm really curious how they're going to unlock them... they'll all be useless on their own so giving them once every 5 levels with job quests would be pointless.
