The problem with gear no longer being learnable is that BW tends to itemize their gear poorly.
Example: Patron armoring. Is there even a companion tank with cunning as a mainstat? Because there's no tank AC with a cunning mainstat.
What were they thinking with Patron mods? What was the point?
So basically, I'd be less worried if I trusted BW to itemize gear well.
Well, the HK droid uses cunning, and he's... DPS... nevermind.
Seems like there was another companion that can use cunning or aim.
I suppose if you're pushing the cap, you could switch to add endurance when more cunning would be of marginal benefit.
