Hey Sicc,
readed the last two pages about that new FE and in my opinion the spell just need to be reworked or totally changed to be a good choice to cast for every player. I don´t like theory crafting and perfect rotation and I don´t want to do this in future either, without my dps is equal to players in top guilds and thats fine ( without cheating
). But with all this coefficients there would be just a handfull of owlkings handling this new spell with a dps gain...probaly only under the influence of cocaine or many much coffee
So I beg you to write that feedback, that you gave here, in the official wow forum
