Just a heads up to those folks who may end up in the same position as me.
I designed my build to be a versatile melee for end game (yes, I realize melees are inherently gimp in endgame now), and Artie 1 looked like a very tempting combination of unlocking UMD, Magical Training, and Wand & Scroll Mastery.
But you only get two of those three. Wand and Scroll Mastery, while a Tier 1 ability, requires lvl 2 Artificier. I didn't notice it until actually taking the Artie level. When the expansion was on Lam, this was not the case.
But now, apparently, Arties aren't as good with Wands/Scrolls as clerics.....
While it seems to me that this has to be a bug (and I even submitted it), we haven't heard either way from Turbine, and it is not listed on the brand new Known Issues list on Lam.
I'd love to hear from Turbine before I go and redesign my toon....
