I want to get into a good HM guild because downing heroic end bosses is what appeals to me. It seems in my time playing that I've gotten with groups that progress too slow, aren't run right (people don't show up or do mediocre and yet are still kept on the team) and I don't get the level of progression down that the best guilds on my server are looking for. If you don't have the gear and experience that is almost at or at the level of the really good guilds they don't want you.
I consider myself to be a smart informed player with a good attitude and I believe I can hang with really good players. I have a good mindset that focuses on finding out how to improve my play, stay positive and learn from mistakes. When learning a new fight I always seem to come up with ways of improving my performance and that of other group members even (though I never force my ideas and usually offer it just as something that they or we could try out). I try to learn from every pull. And I try to respect others points of view and be polite/respectful while still having fun. It seems that most high end guilds don't care as much about that as they do how much gear you have and how many HMs you've downed.
So I'm curious to ask players who are in top guilds (like rank 2000 or better in US/EU/whatever region) how should a player who is say 483 ilvl and 6/6 MSV, 3/6 HoF, 2/4 no HMs yet (though I've watched many videos) currently go about getting into a guild that will realistically kill heroic end bosses pre nerf or close to that? Can any of you who were in a similar spot as myself relate how you overcame the barriers to getting into such guilds?
