Being able to decide on your talents depending on the encounter is all I'm asking for, and is absolutely amazing in itself. There are plenty of additional choices that really do not matter, such as psyfiend vs dominate mind.
We will go OoM so fast that unless the target will die very fast, VT+SWP will have to go on targets to maintain mana, which is no different than today. In fact, for prolonged AoE phases, we will probably have to maintain 2 or 3 VTs on targets in order to not go OoM while using mind sear.
And a very serious question: How does having a talent which resets the CD on MB and makes it instant, in any way negate the effect of haste reducing the CD on MB proper. You're telling me that you always have a MB proc before your next casted mind blast would've occurred? Even if you have a proc for every MB cast except one, it's still better to have that reduction than to not have it at all.
I agree completely that the mastery is complete shit. The procced spells need to have the ability to proc things just like the normal spells do, in order for it to be an adequate mastery. As it is, it's literally just a second crit roll just for our dots. (Though it does give the ability to have a x4 dot tick, effectively)
