It's been rare that i haven't hit a pug TS without all of the above happening.
I've always counted it as part of the fun for the old Tempest Spine .
Really, i think if it really bothers you that much just run her in guild and don't even bother looking at what the puggers are doing.
Me, i kinda like the chaos approach most parties take on this one, and have met some people that were willing to learn the run properly, and some that seem to in the party just to provide comic relief for the rest of the group.
As far as LFM's that seem a bit 'Kyber' goes, i just don't join them, nothing else to worry about there i reckon.
Coit out~
