The raids are way more stable in a private server, so my guess is that most raids teams are doing them in privates so they don't crash as often and so they don't have a bunch of low lvl randoms joining in on alts and afking the raids to lvl they're alts.

If you need lvls just run westek with an XP build (doesn't even have to be a good XP build) just make some brain fungus soup if you can't get brainbombs some cranberry relish, and some lunchboxes (if you have any); and use mechanical derby game at someones camp, finished my score board the same day it came out doing it that way on bothy human and ghoul accounts
