However, the layering of CC in both Arena and more frustratingly, RBGs, has created a situation where healers spend too much time waiting to use an ability compared to time spent in actual "combat". "Limitations" are a good type of CC, but not actually being able to do anything for 15+ seconds at a stretch is simply not compelling gameplay.
Specifically, fears are too long, and stun-locked from 100% to death is common. Snares, roots, silences/interrupts, magic school lockouts, etc. are fine because at least the healer can still move or use abilities.
