Sorc relies on weapon skill line for spammable. I suggest the following:
Crystal Frag- has the stun mechanic added back to its function and removed from crystal blast.
Crystal Blast- remove the cast time. Each cast of the ability grants a stack of explosive shards and deals 4500 magic damage on the target. After the third cast, the the shards explode dealing 8,000 magic damage and 12,500 magic damage over 10sec. After the explosion the opponent is set off-balance. The ability currently stuns and I think the stun mechanic should be moved back over to crystal frags as it always should have stayed. The numbers can be changed for balance but I think this should happen!!! Let me know what you think
