You could... Somehow fit Mark of Rodgort on to your bar, or run with a pack of multiple SF eles. A lone SF by itself is far too cumbersome for my taste, their strength comes in groups, where damage can be maximized and SFs spent reapplying burning is minimized. So... Ah...
Hmm... either:
1) travel with other SF eles, spam-happy heros work just fine for this
or
2) Switch to another build. AoE-ing the shit out of stuff with Savannah Heat and the like works fine too, and warriors will appreciate all the crits (Bull's Strike is now a wonderful PvE skill!

)
For a more support-aligned approach, Mind Blast with a couple of low-recharge damage spells (Fireball and its new-found cousin Smoldering Embers work fine here), and you can use the huge energy gain from Blast to fuel... HEAL PARTY! Oh, happy days for a Fire ele.
