two weeks of ‘dedication’ ? Some guys have been dedicated for 1-2 years or more, with the same Guild. Yet you expect to get carried by the raid guild and get shiny new toys, ahead of a line of guys who have been paying their dues for much longer?
The suggestion above is golden. Tell them what your goal is. Be confident but not some overbearing nerd about it. Above all, be humble. Tell them you’re gonna do something like tag along for some raids and then do it. After the raids, ask for advice from the guild on where you went wrong.
Read the adventure guide and watch YouTube videos on how to avoid boss mechanics that wipe the raid/kill people who don’t know how to mitigate damage at the rirgt time. commit to changing what they tell you to fix in their feedback. Be humble about that feedback. Even if they are jerks about it, acknowledge the fact that they are where they are for a reason, and to them, helping you get Better is like a parent trying to teach their kid how to wipe its butt properly.
Then come back in 5 months of consistently doing those things and see if your situation is the same.
