First and foremost start out by insulting the party leader's main job. Saying that DRG is gimp and worthless is always a good way to make sure you start the party off on the good side.
Second, when the ninja has an emergancy come up and I invite a paladin, make sure that your job as a white mage is covered by telling me that you are leaving because you *quote* "didn't come here to play with a paladin." *quote* Because god forbid you would actually have to do anything other then cast haste and actually *gasp* have to cure people.
And finally, the most important part. Make sure you ditch the party when the party leader is 600 tnl and another member is 1000 tnl, without means of emergancy other then the fact you don't want to do anything. Not to mention you could never forget to not invite a replacement at least for ditching a party for no reason.
Congrats Cloaking for showing me new heights of ***-hatterie and reminding me why I quit the game in the first place. You have earned a wonderful place on my blacklist.
