Then find a guild with higher standards. A guild with an established background that proves they know what they are doing. Start as a trial and prove your are worth being on the team if you don’t have a great record to reference. How is finding a good guild so hopelessly difficult? Are you at least willing to use the recruitment forum and realm transfer?
If you’ve had some bad experiences then try again. With this defeatist attitude you aren’t going to be garnering sympathy here. If you are good at playing ret people will want you.
