1. Well then disregard 8 out of 10 groups and join the other 2 out of 10 groups then. That "hurdle" doesn't seem too bad to me.
2. Argument? I'm not arguing for or against PL my dude. I'm arguing against people wanting others to not have a choice. Me acknowledging that ML has flaws doesn't make PL any better. Because PL still has copious amounts of flaws, but I don't find it necessary to throw out either. Make both better, and the game gets better. Removing something isn't always the best option.
3. You're right you never actively said it, but the vast amount of those tickets were from people complaining about items being ninja'd. Which, is still abuse of the system, is it not? If you join a ML Pug raid, 99% of the time it's gonna be a MS>OS with rolls. Maybe an item or two on reserve for the raid leader and/or friends. The only time other people choose whether you get gear or not would be in a guild loot council system. And if you don't want to deal with that, don't join a guild with loot council. Or join a guild who embraces PL. If you join a guild and you don't like how the officers treat loot, leave and find another. These are not mind-blowing decisions.
4. That's not a bad idea, but at the same time, I play an RPG for power gains. Maybe the immense power gains of say, legendary rings, arcanocrystal etc are a little much, but I think having amazing items are a good thing. Having a 1% increase per item is boring as all hell.
