The Drifter taking fall damage really threw me off the first time it happened on the Earth level, because I damn near died from it. I ended up spending the next couple minutes hiding behind something and dropping stimpacks until my health was back up to snuff. It wasn't a problem for me after that barring a couple of glitches - in two separate instances I was trying to jump up on something, he got stuck in mid-air, hung there for a couple seconds like it couldn't figure out what animation to process, and then I took fatal fall damage and he'd ragdoll. It would have been pretty funny if I hadn't been so annoyed.

I've heard that about the Tennogen stuff, so maybe there's nothing to worry about there. I know the saying is that the endgame is FashionFrame but I generally don't go in for Tennogen on Operator accessories since you're not going to be seeing them 95% of the time - any suits I have for the kiddo have been bonuses in the packs, so I look at them as nifty freebies more than "I want that look".

As far as more Drifter sans powers goes, I could see them doing more with him if they go into flashback missions for what happened with him prior to the convergence at New War, but as far as content going forward goes I foresee them keeping him powered up.
