Something has to be done about the Arena lockout (suggestions welcome)

It is kind of annoying to be locked out. When I go to play the game, I want to actually play. I don't want to wait while someone holds me in battle to save their spot or whatever. We only have so many battles, and we only have so much time. 'Oh that's just the way it is, compete... blah blah blah.' Yeah, I do. And it's annoying. Especially if you spend crystals to refresh but they didn't tell you your team was being fought or locked into battle. I've yet to spend crystals, but I have read that complaint often enough, and I agree.
