I came from WoW, leaving very shortly after they started across server pugging, making it mandatory for the heroic dailies. WoW always had a problem with rudeness, this new pugging system escalating it tenfold. I was a dedicated raider, in a raiding Guild, and was highly gear/achievement oriented. I also enjoyed running lower instances (including lower raids) that would give me nothing I could use simply for the fun of it or to help out. I also pet tanked. I was relatively new at it, tanking just the three easiest heroics, but think I could have gone farther.
What killed it for me was End Game mentality. The pre 80s game (80 being level cap then) was completely different than the 80s game. More than once when a loot fight broke out I would simply say "forget about it" even if whatever loot it was something I needed. No piece of loot was worth the ruckus people would put up over it. I took raiding seriously but the abhorrent manners displayed in end game simply was not necessary to be a serious raider... at least in my eyes. I believe that there is never a situation that can be helped by bad manners and that anything can be said without being a #######.
That is why I quit the game. I came here, hoping this kind of attitude was not here. I was wrong... after having reached level cap here and having talked to folks who have played other mmos, I have come to believe that this attitude is present in all MMOs at end game. From what I have seen, it is not as bad here, or at least on Riddermark, than in WoW (on the 2 servers and innumerable guilds I tried).
I like to raid... I actually love raiding. I love the challenge, I love working as a team, I am one of those people who researches and discusses an instance before he tries it the first time and, if not successful, analyzes mine and my fellowship's performance afterwards to find out where we went wrong, doing more research, and going again. I think this is a blast. I love the complexity and I love expanding my skills to overcome each challenge.
However, I hate the attitude I see at endgame and, hence, remain in my Moria gear, am in a casual, helpful, and friendly kin, and have had to change what I like so I do not miss raiding and instances so much. I spent a couple of months out of the game to adjust my mindset to handle not running as many instances as I like, rather being satisfied with the content my wife and I can do alone, or with what I can do with my kin. Luckily, my kin is working on grouping and instances.
I do not know many instances, however.
I know how to play my class and was considered halfway good in WoW and am told I am good in Lotro. The thing is I do not know many instances because I have never been in a large enough kin with as many instance runs as I like. If I PUGed I would know more of the instances but I have what I call "WoWburn" and have heard of the stories of rudeness in PUGs in Lotro. I have seen people slamming others in GLFF.
So, while I love to raid, run instances, group (and am good at it), my intolerance to rudeness has ensured that I am never going to reach end game here or anywhere else... unless I reach it along with my kin.
I wonder how many are like me... good groupers/raiders who do not raid as much as they would like due to elitist attitudes.
