Some color for Granite.. lava or crystals really don't make sense for a power named granite
Weaponless animations for non-weapon specific powersets
Weapon in hand animations for brawl, boxing, etc for weapon wielding sets (Broad Sword, Katana, Dual Blades, etc)
Weapon in hand animations for part time weapon power sets (Ice Melee, Fire Melee, Stone Melee, etc.)
More whips (+ chain whips)
Sai claws or dual blades option
Throwing daggers, sai, etc.
Lots of good mentions already. Trying not to repeat. Apologies for any repeats.
