I just find it ironic that flamestrike is such a rarely used spell for Fire mages right now when our weapon's very name is Flamestrike.
A bit more on topic, though, I am at the point on my AP progression with Felo'Melorn where I have to choose between the Aftershocks trait or to start working towards the Blast Furnace trait. If Aftershocks really is so terrible that it still does not make Flamestrike worth casting in even most AOE situations, then it should be looked at. Either move the Golden trait to something else or make it so Aftershocks does more damage on its own but cannot benefit from flame patch. (As flame patch benefits was what was causing it to be OP in beta, yes?)
