More moves, but not in the way you think.
I would like that every skill got a different variation if you use it in the air. Giving more variety of way to fight and combos. For example Biwa is support/stun but that could change if his skills got different variations, or arrow bda which is well known for running and attacking from a distance, they could atack close too!
This would make everyone being able to fight in the way that they truly want to fight, making pvp less predictable, it will take longer to master a breathing/bda making fights require skill and reducing the spam.
If you use a move it puts in cd the another variation for balancing purposes.
