Depends on what you are doing. For example-
In pvp this build provides really good burst and its just really fun imo-
1.Windsong
2.Feral lunge
3.Lightning surge or earthgrab
4.Hailstorm
5.Overcharge
6.Fury of air
7.Earthen Spike
This build provides a lot of on demand damage and burst with short CDs and just some rotational damage. Its extremely fun. Overcharge brings lightning bolt back into the rotation, Earthen spike is instant damage and causes you to do 10% more damage for 10 seconds so during that window you can pop windsong, hailstorm, feral spirits along with some lightning bolts and just blow people up in RBGs and arena. Im sure theres other builds you can go with for pvp, but this one is extremely fun to play with and provides really good burst damage as well as decent rotational damage. Fury of air along with hailstorm and feral lunge give you a ton of uptime on your target as well as boosting your damage at the same time.
As for pve, a lot of stuff is apparently up in the air, but following wordups guide it goes
1.Boulderfist
2.Feral Lunge
3.Cant remember, most likely lightning surge totem
4.Hailstorm
5.Tempest and possibly Empowered stormlash
6.Crashing storm
7.Landslide
I cant really comment much on this build since Ive mainly been pvping recently, but its provided really good results for people who are currently mythic raiders. The pvp build I mentioned is what I found to be the most fun out of anything so far. Its pretty fast paced though since you take windsong instead of Boulderfist, not sure if your a fan of fast or slow rotations.
