So, it seems the new leggies they introduce will be a bit of a cop-out in the sense that they will "simply" give you an additional talent. Going through those that already exist, it seems rather random which row, so most talents are potential targets. Obviously those that contradict each other arent (like the Grimoir row).
What's your guess on which talents locks might get per spec?
I'm guessing:
Affliction
Option A) - Boring: Burning Rush - Finally would give you the option of the "tanky" talent plus movement speed
Option B) - Interesting, but possibly OP: Contagion - Would give interesting combos with AC or ELT
Destruction
Option A) - Boring: same as Affli A), Destro probably needs this even more due to lack of self-heal
Option B) - Interesting, but possibly OP: Backdraft - Would cater to the many demands of having this baseline
Demo
Option A) - Boring: same as Affli, see above
Option B) - Interesting, but possibly OP: Hand of Doom - Again, catering to a strong demand to make it baseline
Option C) - interesting, possibly OP: Shadowflame - Might solve their problem that they can't balance this row to make it attractive, so just give it "for free".
