There is a great solution for incinerate, by removing its restriction to movement while channeling. LE has a great example of a flametrower skill that lets u move, and it feels just as amazing as it sounds. The skill in question is ghostflame with the movement restriction removed tech.
not anymore, the dmg is fine now for s4
and btw you are wrong with almost all points u made, and probably havent touched incinerate since s2. Dots arent inherently bad, necro dots are pretty good.
The problem is the dot dmg on sorc has some scaling problems, Paragon is borked and synergies arent the best, on that account ur right. But PTR did improve it a lot by adding a new aspect and made the paragon not that essential anymore, more power was shifted onto items.
Also the aspect on flamescar is absolute garbage, you are scaling dot, not direct dmg and the aspect does direct dmg. Flamescar is terrible by design. Same story with Xfal, if you scale mostly dot dmg its dmg isnt that great anymore. And the ranks on flamescar dont make up the dmg loss anymore in the ptr since uniques have now the worst affixes and legendaries scale so much better.
It has 2 problems right now, first is its clunkiness in a blaster(all about speed and killspeed) environment. Second is Suspectible to cc w/o utilizing some unstoppable with other spells, before starting the channel.
So removing movement restrictions would be a great way to start tackling these Problems.
