currently, Falling Flame is usable in burning crusade starting zones (silvermoon city, eversong woods, ghostlands, exodar, azuremyst isle, bloodmyst isle).
i don't believe this is working as intended as we're currently unable to fly in those zones. using falling flame (especially the glider + falling flame technique) in these zones lets us get to places we normally wouldn't be able to reach/access, such as the silvermoon city dead scar and the mountains (plus a couple quest areas that alliance wouldn't be able to get to otherwise).
edit: i wasn't sure whether i should post this thread in exploits or exploration. since this seems unintended either way, i posted it in exploits. if this was the wrong place, please feel free to move it.
