It's not as hard as you think it might be~ Just be consistent. And most importantly don't be discouraged! The only problem I think you might face is playtime. You need to be more active. But if you are willing to put in the work and get on more often then why not. Go give the application a shot.
Just try it out, Nobody will see you ''fail'' if you didn't get accepted.. Its nice to be a helpop, the staff team is great and funny...
Also during the wait process increase your resume continue to help people, moderate chat and record hackers. Also always be positive about the outcome and don't be too stressed.
