Forgive my newfound ignorance as I haven't played the WotLK PTR, but with the new talent trees, does Totem of Wrath no longer stack?

While we're talking the new talent spec, why are people putting pts into talents where the spell isn't avail until 75? Wouldn't you be better off putting 3pts into Eye of the Storm vs the lava flow one? I can't count the number of times having the spell push back reduced would've saved an ankh.

Just my 2 cents.
