Lol. in 25 man the only viable progression fights for destro are siegecrafter, garrosh, immerseus ( does this even count as progression ), sha and spoils. Every other fight affliction is just as good or better ( usually better ).
I cant speak for 10 mans cause they're shit ( yes this is an opinion... deal with it ).
No one gives a single fuck about your raid bots numbers, they have nothing to do with progression. At all.
And certainly no one is saying destro is "not even good"... im saying if youre doing progression they are not viable over the other spec due to the significant increase in damage and utility.
