Regeneration isn’t free when you have clear casting procced. Is this working as intended or a bug?
Heard something about clipping the end of a regen to use clear casting procs on both. I haven’t tested since I’m on vacation but I’ll be able to break down mage healing when I get back tomorrow / Monday.
I’ll info dump on this thread if you like all my findings and tricks for mage healing 
Working as intended. clear casting reduces the cost of your next DAMAGE spell.
Id love Clearcasting to affect Arcane Surge
