Holy’s niche is that you can easily switch to disc when things are getting tough, and you don’t have to level up a different character. Same niche its constantly had since they added spec swapping, now that I think of it.
Oh, sorry, you meant a reason for taking them instead of another healer? In a RAID?
- Mass dispel - oops, disc has this too
- Leap of faith - no, while this is unique, nobody’s taking you because of this
- Symbol of Hope - no, nobody’s taking you because of this either, although you would think it would actually be desirable, since nobody else has this and on paper it looks good. Maybe if mana mattered?..
- Spirit of redemption - oh wait, dying generally isn’t a great plan.
I do agree that we pretty much do have a healing spell for every occasion (while the other healers all have a weakness in one type of damage/healing pattern), but its not like our numbers are better than everyone else because of this. Strange. (Probably because everything except PoH/Renew is on a cooldown.)
Thinking, thinking, thinking… Salvation is a 2nd raid cooldown, but shaman has that (SLT/HTT). Offensive dispel… not really used in raid fights, but shaman has that too (Purge). Nope, not seeing anything else.
Mass Dispel is the only thing we bring over other non-disc healers that would be desirable. If only they didn’t occasionally booby trap it (and yes, if you haven’t been around for very long, they DO this) so that “no, you can’t use mass dispel on THIS mechanic, we’re explicitly making it unusable on this fight by wiping the group if you try” it would be stronger.
