While I'm not in favour of those party, I also dont mind them that much - and I joined some in the past. Since we're having the token-system I'm fine with joining such a party once I got 60+ tokens since at that point my mind is set on busying the bird anyways and I'm not bothered with rolls that much anymore. If I can get a one-shot party, I'll gladly take that over one thats struggeling in phase 1 of [insert primal] - granted, the lootmaster-rule doesnt mean that its a good party, but if it turns out to suck, I'm out *cough*

So, reasons to join one: Not being that concerend about getting the bird (because I either have it or have almost enough tokens); light for my relic (by doing something that isnt AS1); points for my last tank-mount...
