ISF turned destro into a huge drag in Cata and all that's happening in MoP is we have that same drag of a 3 second cast, now with huge ramp up of 10 embers and no empowered imp proc or soulburn to at least give it a chance for instant procs. Pyroclasm is a terrible option that replaces 3 boosted incinerates that spends all 3 charges of backdraft on chaosbolt for just a 30% cast increase.
There is nothing in the game even close to having so many hoops to jump through after a huge build up comparable to building 10 embers. In fact, most mechanics that require that kind of build up get INSTANT casts. Anything else with a 3 second cast has instant access. Anything that requires lots of ramp up akin to building 10 embers gets a very practical to use reward. Chaosbolt is the worst of both worlds double gate.
How is something like a 1.5 second cast chaosbolt that refunds some mana not an option? Does it have to hit for what it does now at 1.5s cast? Of course not.
