What would prevent 0/1 Healer clears of content?

[Niroken]

I think this approach focuses on a particular tree and misses the forest. All of (1) - (6) are about healers wanting to feel relevant and wanting to have fun. The zero healer clear of TOP is, my two cents, a gut punch that highlights how not relevant a healer can be in content across the board.

That is exactly it. How would you think DPS would feel if healers and tanks could run content just as fast without DPS characters? The forums would light on fire.
