Another comparation between AST and WHM

[winsock]

I'd like to reinforce that all this complaining is not about wich class is better, but about WHM keeping the tank alive with ease and AST having to use all their skills and resources to do the same job.

If WHM and AST had the same level of ease keeping the tank alive, what reason would there be to play or take a WHM? Repose? Stoneskin II. The only major perk WHM has is potency.
