Perhaps DoT was not the proper wording, she isn't a burst mage, more consistent damage, but not exact damage over time spells. The Ult with Rylai's and Liandry's would work well, along with her W.

On her Q, to better elaborate: I had the idea to make it more Syndra's Q, but since I understand you DON'T want that, I have a better idea:

Make it an ammo system, so she can place several flames in succession, with a charge time, and allow her to detonate a flame, with added CC, but a cooldown to the entire ability, restricting her use, but giving it more utility.
