They should raise the skillcap of companions rather than just re-slot it.

Why pretend that it's customization when it only makes sense to stick to one route.

I hope they add mobs that can ONLY be soloed with a powerful companion. The potential is great but there's just no content in the game that requires the companions to exist. This would be good area to expand in a patch instead of just slapping a few more fates into the game.
