FlameWall + Incinerate

People have been telling me this combination is pretty useless and that I should focus on either incorporating one or the other versus using both.

I have been working toward trying to make Primarily a Magic-Find Orientated *Fire* Sorceress; and making use of SolarOrb(2×)+FireWall, then finishing off with Incinerate (/Ember Fusillade).

Am I wasting my efforts with this combination?


Do any of the abilities have any attributions other than Ignite/Burn?
...it Would make sense if Flame Wall were also to 'Hinder' when Ailments are applied,, because they're walking across Molten-Ground. :)
