Do people think that a Dragon Lord should switch to the Spellblade instead of trying to be the New Elementist? With how much they seem to focus on all their active abilities and applying stacking debuffs for greater power (which are increasingly easy to remove & cleanse), I'm not sure that it works well for someone trying to use the Dragon Breath as a Nuke, while a Spellblade gets bonuses for both arcane damage and melee damage, gives you an option for a critical hit build, and gives you better increased resilance.
Doesn't help that I don't know yet what abilities like 'Elemental Mastery' actually do. The Hero Builder really is flawed in that if you try to pan over a highlighted word, it vanishes before you reach it.
