Thx for your arguments, Musica. It all sounds logic and interesting.
But there are some other points too:
The diference between FBB (Fireball Barrage) and WH (Withering Heat) is also in range and speed debuf.
FBB has only 80, WH has 100 ft range. With WH, you can reach target better and slow his speed, which eventually leads to the kill, but yes, its just single target, FBB is AOE, witch can be more viable in warband vs warband play. I will try FBB today for sure.
Ignition - very good tactic to debuff corporeal resistance for you and ALL your mates with your first spell (ignite), but again it's just single target, for assist train.
Flashfire tactic was changed right? Half the time and you can move while casting, still good.
The Burning Head can be game changing in keeps/forts because high singe and AOE damage and AOE morale drain. I have never used this before in combat, will try it too.
Any chance you will get 1 more mastery point at RR80? That way, you could keep BH and Nova too
Anyway, thx and let the testing begins.
