I found it rather frustrating playing a Wizard right now, most of what I'll do just messes up the team because so many of my abilities have some kind of AEO and the environmental effects are everywhere and can completely mess up your party beyond belief by complete accident. There's been so many times where I can't do anything because of the environment getting in the way and potentially messing up allies. I will say if you can get on higher ground the damage buff is amazing but it just feels more frustrating so I have to agree with you geala on that front. I may go Wayfarer and use only healing magic to help with helping the team.
So far our Rouge has easily been the best at dealing out massive damage to a single target and definitely recommend. Though it might be different by the time of full release.
