ADVANCED DRONE should be renamed to Superior Drone, so other feats makes sense.
Not the only issue. "Advanced Companions" don't exist, so we have no frame of reference for what should change about a companion when you take the feat. The Pathfinder Equivalent "tier" of companion is "Specialized Companion," but that's what the playtest calls a companion augmented by the 18th level feat Elite Drone, but there exists no such "tier" for Companions at the moment.
If you're not testing at the very highest levels, it's probably best to change Advanced Drone's name to Superior Drone and have it make your drone a specialized companion. If you are at 18th level or higher, though... I got nothing.

I mean, there are Advanced Companions, but those are specific Animal Companions introduced in Howl of the Wild, which level-gates certain companions (like Griffons and Riding Tarantula). So if the intention is for there to be Advanced Robot Companions, there probably should be a note from the Design Team that those are coming in the source book.
