Sorry if I'm dense but I don't get it : if we can upgrade the blast via feats when multiclassing, is there ever a combination where it makes sense?! I mean, if its multiclassing with a melee/ranged, its better off using its weapon and if caster, even with the loss of a level it makes more sense casting spells than blasting (or blasting but then why split with other caster class?) It just seems like a 4 feat spend to have a better than normal back-up throwing weapon to hit levers kind of deal...any good builders out there that have found a synergy? Since it doesnt have passive aura via ES it just seems pointless, unlike the monk ones...
