I could personally care less about artificers. However, there is one thing about them that has made me happy.
The construct companions.
The trainer seems to indicate that they can be trained and whatnot, which means that they (hopefully. PLEASE hopefully) will not be dead stupid summons that you can't bring some places because they'll screw it up, and aren't all that helpful in the long run.
But why, why would this matter to me if I don't really care about artificers?
Druid animal companions.
I'll keep on hoping, as whimsical as that may be.
