Why is this a problem?
Currently, even on my crappy geared disc spec, I can do 30-40k dps if I can stand and cast, and this provides quite a bit of healing. In 5.2, I will only be doing this more thanks to Solance and the newly buffed Penance.
With better gear I'm sure it would be higher.
What this means is that bringing a 'Heal-PS' to raid - a healer that can also do decent dps - you are essentially adding half an extra dps player to your raid. Add two, and you have 26 players in your 25.
But wait, why do you care if dragons die faster?
Because either this gives two healers *massive* utility on top of what they already have (Disc is certainly not lacking here, no idea about monks). I mean...40k dps is quite a bit.
This means that either Blizzard will need to balance the actual healing numbers around the expectation of them also being dps.
A better solution.
To me, what would make more sense is to keep the style intact, but shift it more towards being a healer.
- Reduce the damage done by these skills by 50% or so.
- Increase the healing done by these skills by 50% or so.
- If extra utility is needed for monks (no idea) then give it in a different manner.
