SotF is bad on Feng and Elegon. I think I specifically mentioned what encounters SotF is usable on, but better post than read, right?
Really feels like people are fighting a Strawman. SotF and shrooms are bad on some encounters, yes. On 5/6 using shrooms rotationally will lead to huge hps loss. On some of those, situational usage will give you better output (Spirit Kings cleave, Feng arcane aoe and epicenter). On WotE you can use SotF, because raid gets quite a lot of damage all the time from pull till kill. I've got better results as SotF which I posted about. There were NO statements that you should use shrooms 24/7 over SM and WG. There were NO statements that SotF is best talent ever in WoW. You are imagining things which are not there.
