They've tried it twice before and that hasn't been how it's played out. There are a lot of drops at first in the new teams but then things stabilise and characters stop dropping and the queue grows again. Aather would have to become massive in order to reach a size where drops could happen at the current rate but people could still get in quickly. Besides which, more drops means less feeling of stability for the characters.

It is unfortunate that people have to wait for months on end, but honestly the only thing I can see that would reduce apps is to limit characters to 2 per person again, and even that would barely do anything considering the vast majority of players only have one or two characters.
