- Fallen Protectors - 2 healing works fine, and makes certain mechanics easier (less time in Desperate Measures phases), but also means your DPS can't be as derpy
- Norushen - most stringent DPS race of the first 4 (first 8 even), and can easily be 2 healed if the few mechanics are done right, you will have to use cooldowns properly near the end though
- Sha - very easy to 2 heal, and makes the fight much easier (people don't get as high pride), but you will have a couple of tight spots (high pride swelling, one healer banished, etc)
For opening heroics, you should be expecting your DPS to at least be capable of roughly 200k average single target, any less and you may start having issues, and of course, more is always better.
