But on topic, I was looking at the mage tree and thought maybe the whole tier should be re adjusted numbers wise. For example if you doubled the values on unstable magic (60% chance - 100% Damage) and combined this with the new set bonuses, you could technically have close to wrath style game play which could be viable? Like that means at least if your playing MLS for example you can go for the turret style of play, and if your playing RMD you can take ice nova for the burst and the instant cc to help secure kills. So you could actually have a varied set of talents for better game play. Since I have to admit, I myself don't play a mage any more. But I can really see why you all dislike it so much.
Keep in mind I'm only throwing ideas out that other people may not have considered so....Obviously numbers would be tweaked and I am honestly clueless on what could be done to make frost bomb a viable choice, but I know the majority of mages hate that talent as well.
