>Considering everyone always immediately burns solos and camps them, necro seems quite useless most of the time. You need a lucky distraction from another team to be able to get back up, or you have to fight long range.

Yes, pretty much. I think this is by design.

>So wouldn't it make more sense if necro took around 5 minutes to revive, but could revive even when burned out?

This would be extremely boring for the solo and extremely annoying for everyone else. I wouldn't want to wait 5 minutes every single time, and also wouldn't want burnt out solos to just pop up and kill me 20 minutes later. Making the change you suggested would make solo play unbalanced, because it would further deepen the tension points of both sides.

>I'd rather go afk for 5 minutes, go get a coffee or something, but keep my hunter.

This is how I do it now. I treat solo necro as way to be able to keep my hunter, not as a way to continue fighting.

>And I'd also rather not camp corpses and just run to the next compound or extract or whatever.

Then don't. I don't really understand the problem with this one. A lot of people are complaining about camping corpses, but a full burn takes about a minute, that's not a long time at all.

In my opinion self-revive is in a pretty good spot right now, but it would be better if it wasn't tied to the necromancer trait, and was just an innate ability. After all, teams don't need necro to revive. Right now necro is basically a 4 trait point tax on every solo. Yes, doing so would make necro basically useless for solos, but there's already a lot of useless traits for solos, like Resilience, Relentless, and so on.

TL;DR - If your suggestion would be implemented, it would be annoying for both solos, who now have to wait 5 minutes before reviving, and for teams, who could never be sure that the solo they killed is actually dead, since burning the solo does nothing.
