If you are a WHM without Swiftcast, you are holding back your team at endgame

[Doo]

Because people are acting as if it should be mandatory to have a skill used mostly for when other people screw up. If it's sad to see so many people against this it must be catastrophic to see how many people need a swiftcast res to make it through a boss fight.

It's mandatory because it makes life so much easier for a healer rather than because you need to use it for someone who messed up. Your job as healer is to save lives!

Also someone could die from:

Getting accidentally setup by other players - ie titan plumes.
Healer too slow on heals for whatever reason.

But it's not the reason that matters, it's the healers role to do everything they can to keep the party alive.
