After weighing all the arguments from varios posters, I think the whole debate can be summed up into 3 simple things.

1. Emnity generation/MP management are key in end-game content
2. WHM have high emnity generation and poor MP managment
3. WHM are inferior end-game healers

I'm not agreeing one way or the other with this, I'm just pointing out the conclusion most arguments are drifting towards here.
I still firmly believe SE should have adjusted SoS or given WHM back some of those MP restoration skills from 1.0. Not like it would hurt the class at all to make them more competitive in Coil.
