I don't even know about it being a melee move. His shoryuken was never really that useful, even though it did actually have some invincibility on it. It's because the range was so small considering its damage output. Meower's slide tackle is way more useful of a melee attack on a mobility class; it had multiple uses, did a lot of damage, and was fairly easy to hit. On a side note, I'm going to give Jaina's dragonheart (shoryuken essentially) a lot more range/fire projectiles that extend out.
I'm thinking of making it a projectile that explodes at a predetermined distance or if it hits an obstacle. Does little damage and sucks people into a vortex that does some damage over time. It'll probably cost 1 ammo and some energy.
Also, speaking of revamps, I'm going to re-do some of Asiafat's stuff. His M1 attack is okay, but I'm not satisfied with his M2 attack. It was a bit of a cop-out implementation that was easy to code. Since his role of team support is going to be usurped by the Red Mage, I definitely want to change his M2 and maybe his M1 attack too. I was thinking something similar to the GES BioRifle in unreal tournament. Chargeable acid goo that you can shoot at dudes/obstacles. Gives him some dangerous but slow attack area denial, or arcing fast projectiles.
