I’ve read a lot of proposals for changes to the Skiitari, but none seem to emphasise this.
I think that the servo skull should become a passive companion that retains its function to do puzzles and shoot enemies, but choosing another blitz just removes its ability to be amplified.
The servo skull seems like such an integral part of the class’s identity and uniqueness, that it really doesn’t make sense that it gets removed completely when choosing another blitz such as arc grenades. Especially considering that you can customise it.
What’s the point in having these cool looks for the servo skull if choosing any other blitz removes it from the game?
