And I can actually agree with a couple things you say.
#2 and 10 are the only ones I have a problem with. Weird builds that can't survive without twists were commonly known as bad builds. Think about it. And #10, if you pug you may be interfering with someone else enjoyment. Perhaps they are playing a weird build because they want a challenge, or they are newbs who don't have the quests memorized yet and would like to play the quest and learn for themselves, not chase an uber powerful weird build through the quest. There is no sense of achievement and no chance to learn anything from this kind of behaviour.
So if you solo, knock yourself out.
If you group, have a little consideration.
I for one, have no use for twists, as even with my completionist toon, I generally like to play the quests and enjoy myself and not get caught up in the mad rush to an endgame that doesn't exist. So even in my TR groups, I would respectfully ask you not to use them. But I probably wouldn't toss you for using them either.
It would be nice for an official stance on this so we could forget it and move on. The debate is getting tiring.
