As somebody who has dealt with recruitment, you sound like an applicant who tells the guild how good you are, but don't actually have anything of merit to prove the claim. Here are the *baseline* expectations for getting into a top 50 guild imo:
- Extensive heroic raiding experience
- Recent heroic raiding experience
- Heroic end boss kills
- Part of top region/world individual kills
- Verifiable performance through recent logs (strongly prefer heroic boss logs)
Now if you're applying to guilds outside the top 50-75, then I think these standards are much different, but a top 50 guild isn't just going to "give you a shot" without thinking you are very likely to succeed.
