Relic
The relic seems basically the same as the current 15 badges of heroism.
Badges of heroism item:
[Totem of the Elemental Plane] (196 haste, 10 secs)
New item:
Totem of Electrifying Wind - 200 haste, 12 secs
So, unless the uptime on this totem is close to 100%, which seems unlikely, this totem looks like it will sit around unused.
Set Bonuses
2 piece makes rotations longer, gives about 1500 extra damage per flame shock, and allows us to use less time refreshing it. Not terrible, but nothing special
4 piece bonus, a quick back of the envelope calculation:
Assuming lava burst averages of 12k (Probably reasonable for t9 gear, perhaps on the low side), the 4 piece bonus will push that average up to 14.4k, for an extra 2400 per lava burst. If we're casting lava burst every 10 secs (Again, not the tightest rotation, but not terrible), then it's 240 dps, and it will get better if my averages dmg and rotation times are conservative.
Overall, not bad, if a little dull.
Badge gear
Another worry I've got is that yet again, the first pass of badge loot doesn't have anything an elemental shaman would want.
Helms/shoulders, there's an mp5 and a physical dps item. Rings, there's either a spirit or mp5 option only
The +hit trinket isn't horrible, but doesn't exactly fill me with wonder.
This is exactly the same as happened with emblems of conquest. Both the badge items, and the runed orb recipes were of very little use to elem shammies, unless we were willing to drop down and use cloth/leather items, and they make 5 different necks, and none of them are much use to us, unless we have very bad gear already, as so much budget is wasted on useless stats.
