Personnaly, I switch to WHM for the upcoming raid tier.

Let's be honest however : I still think the lilies system sucks (as well as plenary indulgence).

But the reason I made this choice was because I think WHM has now an awesome recovery ability thanks to his great pool of mana, Assize to 60s, Benediction to 3min, Divine Benision as an insta shield for tank buster.

I have now have no fear to cast some Cure II because I know it won't hurt my mana while I casted more Cure before to have the free cure II proc.
Same goes for aoe healing and espically medica ii that is powerful but cost a lot of mana.

So, don't get me wrong, I'm not saying WHM is fine right now, but there are some changes they made that I really like and make me really confortable to play it.

The fact that I can have 2 free raises and others strong healing stuff sounds good for me during learning times.
