To play on the server and I find I can never get anywhere having to wait
Around ages for groups for instances etc...
The answer to that (for levelling instances like XAES, Lab 13, etc.) is the Mercenary Contract. This allows you to enter an instance, summon the Mercenary Captain, and talk to her to hire mercs to fill out your party. They are not as good as human players, but they are pretty good. Each one has an AI suited to his/her role (stand back and heal, stand back and fireball, jump in and hit with axes, stand back and shoot arrows, etc.) and they give a very disciplined-looking appearance. (Compare GW1 heroes and henchmen who are undisciplined maniacs.)
