If these new mobs were better than any other camp...literally everyone (including bots) would go there and nobody could get xp from them.
The point was to have something different, an outside camp and some different mobs people specifically asked for. Potentially a better camp for a party of friends to goto instead of mindless cleaving in a laggy dungeon.
MMO player mentality: if something is the best, then this is the only option to use now.
They should of called them Beta Collibri not Locus.
Also it's been a long time but I'm pretty sure you can go to the camp and cast sleepga2 on every collibri mob and logout, then the bots will pull them and wipe over and over again when they sleepga their entire group on every pull.
