Depending on how fast 'quickly' is, we might have the potential to spam our soul shard super spells, and then just run / teleport away and get out of combat for a few seconds, and regen them back. Seems like it might be a cool little strat.
It's really going to depend on how fast it takes to regen one once out of combat. (I.e. if it takes 30 seconds, it's not worth doing nothing for 30 seconds, but if it's 5-10, it might be.)
What do you all think?
