Your combo has a flaw, since empowered Q consumes all crystals, and W+E would only give a total of 3 crystals, the ulti would be unusable. Not sure which combo would be best, but starting at 3 flare crystals and then using E->Q->R->W seems to deal the most damage to me, also leaving enemies in the shocked state so your Q can go off cooldown while they can't do anything.
