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

[Boyahd]

Why shouldn't you attempt it? It's not like the world is going to end if you try and fail. It's a game after all. That's how you learn. Swiftcast is definitely good to have, but when I hit 50, no way I'm going to wait for another 26 levels before trying endgame.

I'm not trying to tell you that you CAN'T attempt it, and I'm not even demeaning your ability as a healer. However, I still feel you would be a far more effective WHM/SCH if you have Swiftcast in your arsenal for end-game. That's the long and short of it.
