probably because helya other than guarm or odyn is indeed like tailored for fire
as she needs burst ae and burst single target on a few occassions which is what fire excels in
good that helya doesnt need high single target dps like guarm/odyn do as that is where fire looses hard
but oh well .. why do i even try to explain how a specc works when you guys are only capabale of:'i have absolutely no clue how fire works but: OOOOOOOOOOOOOOVERPOWEEEEEEEEEEEEERD!!!!!!!'
