For anyone wondering, Artificer max Evoc DC is now equal to Exalted Angel Sorcerer, even when not using Epic Increased Potential. Their Evocation DC is definitely workable now.
I'm thinking Artificer could be okay if Battle Engineer also gets some tweaks. With the number of feats they have a Ranged/Caster hybrid could be decent; Arcane Warrior is pretty strong, for a Destiny feat. I don't know cast time/cooldown on Tactical Detonation but it could be a fun spell.
Add some ranged power and bonuses to crit range/mult in Battle Engineer and you're probably like 80% done before you even get to the actual pass.
