The other bosses are too easy compared to Garrosh normal IMO. It started getting more interesting on the last 5, but honestly they are like the rest of the instance should have been (after the introduction of flex).
Don't worry, you can count Norushen to be down too. Sha of Pride will be the first boss harder than normal Garrosh.i got 2 heroics down atm, yes it is too easy And i did not find them exciting, only liked garrosh and siegecrafter,
