In your two posts, essentially all of the focus is on the talent changes. Do you like or dislike the baseline changes (mind blast baseline 2 charges, swd baseline, making voidform a talent instead of baseline, etc)?
Since your first posts says most rows do not need fixing and just tuning, does that mean you are pretty happy with how Shadow plays currently but just think it needs some tuning?
I understand that talent philosophy that Blizzard has mentioned, but I do not tend to agree with it (and they often seem to not agree with it themselves). You even mention having Reaper of Souls and Shadow Crash in same tier which would go away from that philosophy.
For lower non utility/cc tiers, I generally have more of a philosophy of choosing 3 of the 4:
Push a button more often
Have less button pushing
Keep the button pushing the same
Extra button
And even that is pretty general.
That general philosophy difference addresses most of what you said outside of Tier 6 and 7.
Tier 6 is already a cooldown tier (as you mentioned it should be), all have different situational use (as you also mentioned), and all synergize with Tier 7 as far as I can tell.
Why do you say S2M assumes Voidform? S2M generates more Insanity which means longer Voidform if you choose it, more Voidbolts if you choose CoP, and more Devouring Plagues if you choose Devouring Plague. Also gives you that sweet casting while moving effect.
Tier 7- Thanks
