Moving to the group composition forums.

Yep, mana stream no longer stacks - the flip side is that a single totem now gives 91 Mp5, which makes the 3 x Healing Stream, 1 x Mana Spring quite viable. Before it was either all one or all the other mostly...

There a are few things to consider with ToW Glyph -

1. It doesn't scale with spell power - its a flat 84 spell power, and thats all it ever will be.
2. Requires spec'ing into ToW - obviously, right? But pre 3.1 if you were spec'ing into ToW, you only needed to do it on one of your toons.
3. It's taking up a major glyph slot - Glyph of Lava and Glyph of Flameshock are still probably the two best glyphs for ele shamans, so by taking this you're giving up a glyph of lightning bolt, shocking, stoneclaw totem, thunder etc...

Don't get me wrong - it's not a bad glyph. It just that there are a lot of great major glyphs for shamans now...so it's not such an easy decision.

As far as I know you keep the buff even after the ToW is gone, so you can drop ToW's and then all your fire ele's if needed.
