They both have the same cast time, mana cost, range, etc and I can’t see any difference between them, so why not just always cast Mass Resurrection and never use Resurrection at all?
It kinda seems redundant. Is there a difference I’m missing for why they both exist?
Resurrection is usually available on the non healer specs of the classes that have it, whereas Mass Resurrection is healer only.
I kinda wonder why Resurrection doesn’t just turn into Mass Resurrection when playing Holy or Disc instead then, there are other abilities that do that based on spec.
For those times that you res your crush in the party and leave the other competition lying dead in the dirt.
Sounds like you have experience in this.
Some people don’t deserve to be rez’d. Make 'em walk.
Mass Resurrection is also limited to people in your group, whereas the regular flavor can be used on any “friendly” corpse.
That is true, I did not notice that difference in wording.
None healing specs don’t have mass rez.
Well, for friends, give them a rez with the ‘Brazier of awakening’. Nothing says ‘You barely deserve a rez….’ than bringing them back from the dead with ONE health point. 
It’s so you can choose to resurrect one person in particular and screw the rest.
Or if you want to just rez everyone, you can use mass resurrection.
Blizzard hates it’s community, the only thing they love more than hating the community, is enabling the community to hate eachother.
Giving people the ability to selectively res a single person and ignore the rest in an LFR raid, or rez only the tank but not the dps that pulled the extra pack in a M+ run, is vital to the constant need of Blizzard to turn this community into toxic vindictive jerks, at every possible turn.
All I can say is, you guys shouldn’t have complained about removing flying so much in WoD. If you would have just let them remove flying, then they wouldn’t hate us so much.
Instead, we complained, hard, to the point that the Board of Investors that override even the CEO, stepped in and told them to not remove flying.
So now we are in this perpetual state of sabotage from within.
I think the only fix is to fire literally every single manager at Blizzard and put all the remaining laborers into a rehabilitation program, to move them back towards a customer service / product selling mindset, instead of the weird “I GOT THE CRACK, AND IF YOU WANT IT, YOU HAVE TO DO WHAT I SAY” mindset.
I can’t res. But I can tricks threat
This would make the most sense kind of like how cleanses work for the most part
You don’t always want to use Mass ress when you want to make the fail that wiped the group to walk back themself
