I've found the community here to be MUCH more open and inviting to new players, and even other players. I regularly see people apologizing for stuff and people being completely cool with it, and I see people just being accommodating and polite. It's awesome, and definitely leaps and bounds better than what I experienced in WoW. Sure, there's still the occasional jerk who likes to pull ahead, but usually asking nicely will get them to cut it out.
I tank because it gets me the most satisfaction. I love being the person to lead the group into battle, and I love being the person who takes all the hits. In the end, we're just little dogs yapping for the boss' attention, but that mentality of "no, you will focus on ME" is why I love it.
