Now take my Shaman specific examples:
-Keep FB on all the time, macro FT w/ LL. You don't have to give up control to get more damage.
-Keep FT on all the time, macro FB w/ ULE. You don't have to give up damage to get more control.
-Keep either FT/FB on, and macro ELW to heals. You don't have to give up dmg/control for stronger heals.
-Keep either FT/FB on, and macro RB to ULE. You don't have to give up dmg/control for more defense.
-If I can get 40% bonus to LL damage all the time regardless of norm imbue, why not just make it stronger baseline.
-If I can get a snare on ule all the time regardless of my norm imbue, why not make it snare baseline
-If I can get bonus heals/hot whenever I cast a heal, why not just add the bonuses baseline
-If I can get 40%dmg reduction when I ule, why not just add damage reduction baseline
Do you see what I mean by "best of both worlds"? You can have a perma snare, and still have max LL damage, without losing out on any control. Or use FT and still have your ranged slow w/ ule, again not giving up any dps. Have FT equipped throughout the fight for max dps but still get max heals w/ elw when you click heal.
