I was messing around on the PTR checking out the new shaman changes. I have about 1700 spell power without totems.

1) LB spam is still almost as effective as the lava burst rotation. I think I did about 2.4K dps with just LB spam, I did about 200 more dps with FS+LB rotation on a single target
2) Magma totem was doing about 650 damage a tic, critting for around 1200-1300 or so. This is about double the damage it is now, and I'm pretty happy about it. Vs. 2+ targets I think it'll probably pretty much always be more effective to throw down magma as far as DPS goes. It's not as good as druid hurricane, I think my hurricanes crit for around 1500. But it's probably our best single change. 3 or 4 of these is going to hurt really quick.
3) It looks like my 3K spell power shaman with the old hybrid ele/enh spec is doing about the same damage as the new ele PTR shaman. The hybrid spec probably still is up dps by about 10%, but I'm not totally sure.
