So far I feel 50-50 about these class reforms. I'm not sure how MP cost will be affected for spells or anything, so I guess we'll just have to wait and see. -_- I hope they leave tiered healing spells.. they can really come in handy.
I kinda liked being able to use other classes' abilities and customize my character at will.. but again, I think it's better to wait and see how it's all gonna work when the patch comes.
