This seems a little moot for arcane while the mastery remains as it is. Arcane doesn't really make sense without Evocation. There's no potential to dump mana into damage via Arcane Blast which entirely defeats the purpose of the stacking effect. RoP doesn't seem like a very viable option for Arcane. Being at 35% of mana for the latter half of the fight might be fine for the other specs but it does not compliment Arcane.
True, under the current system, but i thought I saw that Arcane Blast was getting a lower mana cost, which would mean your regen would be approximately enough to keep up with most of your casting it, with a few missiles here and there. Also wowhead is reporting the mechanics to allow this strategy very well. However, if the arcane spells remain expensive to cast, then that pigeonholes arcane into one choice: invocation. This is contrary to what Blizzard says it's trying to do, which makes the new changes to arcane believable to me. I guess what i'm saying is: under the current system, you're 100% correct, but i was under the impression that they were making changes to allow it to not matter(or be situational) for all specs.
(This is pure speculation on my part) If so, we might see arcane become a very mana efficient spec with a few dumps to give massive bursts of damage.
