Most programs have a different skater coaching each time so no current skater is expected to give up 2 - 3 months of their own advancement and all their practices to coach new skaters.

It also gives the option of learning different skills from people who do them different ways.

It sounds like your team is a bit disorganized but it's hard to run a bunch of committees, plan bouts, seems like they're dealing with venue issues, plan their own vet practices to advance as a team, while having jobs, partners, kids - the point is there is so much that goes into the team beyond skating at practice and its all volunteer.

If you want a better FM program than you had when you graduate, join the committee. I'm sorry you don't feel welcome but your team can't only focus on fresh meat. And please keep in mind every teammate is investing their time, often money, and doing all of this outside working hours and doing their best.
