Scaling of abilities to a player's level is not a step in the right direction.
I don't see that as a wrong step, really. Of course we will have to rethink our strategies, but that's not a bad thing. Quite the contrary, having tiered abilities was more of a hassle for me than anything else.
Having played a WHM for years in FFXI I understand the thing about hate control, etc. but I seriously doubt Yoshi-P and the devs didn't think about it. I'm really interested in this scaling of abilities.
