Unfortunately I wouldn't expect any changes before 3.0. I think even a small band-aid fix would be to change energy drain. Initially it deals 150 potency and then converts half the damage into MP. You get a trait that doubles the amount of MP you get back. How about making it initially give you all the damage in MP and then the trait would double this. As a couple people have mentioned above, if you're low on MP one energy drain just isn't enough.

Caster gear needs to either be changed or split. Itemization is outright horrible for 2.4. If you look at both sets, it looks as if they didn't take SMN into consideration whatsoever. BLMs have so many build options this patch. Every piece can potentially be used as everything is loaded with spellspeed and they require less accuracy. I know it's too late for 2.4 but in the future, I think that caster gear needs to be split. We need to keep talking about it
