There are all these threads saying how the player skill in 50s has declined. Simple solution: friend people that are good players, invite them to games you create, and if people don't play well (refusing to heal, Rez, stop stomping when it's not necessary, potting for ol etc) warn them and boot if necessary. Do not be afraid to boot someone if they are being ridiculously detrimental to the party. Also, if you want to have a great run with decent players, my (chubbsy or chubbsytwo) vl (soon to be bale fort sewers... hopefully today) are usually pretty fun and efficient. You can't stop poor players, but you can easily avoid them by always hosting your own games and keeping them out.
