How does post patch companion levelling work? Before patch, companions seemed to level each time player did when he had them in company. Fresh post patch game, I am level 10 but ED-E have still 180 health. Is he bugged or does levelling work somehow different?

BTW: I was not looking in to GECK but he seems to have much stronger ranged attack than before.

My level 30 character have ED-E at 396(???)HP

Cass still 335/285 however.

Did you got him before or after patch?

According to the GECK they did lower companion stats and leveling ratio a bit in patch 1.2, which if you start a new game you'll notice, but that sounds like a bug, since I'd think EDE would have gained at least some hitpoints by then?

I am lv 11 and ED-E is still 180 HP. That is his starting HP. I would say yes he should. If something did not changed radically.
