Everyone's open to his own opinion, but I am curious still:
1) You want to raid mythic, but lack the gear/hc experience as foundation for joining a mythic gear right away. How do you go about aquiring those things without joining a guild? HC pugs? O lord, what a way to build a resumé...
2) So you just have to be lucky to end up in a guild that actually ends up going mythic?
You talk about guild switches like they are coupled with legendaries our boss mount ninja'ed drops.
When you work at a job, you do it for the money.
When you play a game, you do it for the fun.
Socialising and making friends at the side shouldn't dictate where you work or how you play the game (provided you do not totally fuck others over, like with ninja rolls or such, not paying on agreements and the like).
Also: badge of shame? are you serious? oh man...
