I've seen good leaders do fantastic by the group by offering help when can and doing what is necessary to ensure the group is successful, ie,. being of good cheer in a talkative by not being an overly chatty kathy, knowing what to do in missions and not completely lost like a newb, and not acting like a total douchebag by being a control freak by tossing players simply because they may not agree with one of the players.
In the past, I've been booted from groups for "offering a beer" in chat (yeah, someone actually got bent over that), offering to seek an object while invis (ninja), getting defeated too many times - too many dies (Yeah I was booted from a farm because I wanted to increase the defeat value on a new brute I created and the leader took offense and booted), and other insane ways people can show in how thin their skins really are.
There is another similar topic about poor leaders that has me rather irritated; when I'm on my farmer and see someone posting for a needed task force or mission and asking for other players, only to get a "oh we filled up and don't need any extras at this time" after I have been told there is a secured spot and have jumped out of the farm and moved over to the other toon which doesn't take but a few moments (No I don't stop at any vending machines etc as this is not the sign of a good player to do when people are waiting). Good leaders show their true ability to lead by being patient when needed and not jumping at every 'shiny" (another player that sent an PM while I'm transferring to the alt) player and is readily accessible for a quicker launch by a few seconds.
Bad leaders can be described in a number of ways and probably a good reason why a number of players find it hard to get groups because simply said; "We decent and good leaders and followers do not wish to tolerate your BS."
