Perhaps have a setting in the Settings Options that lets you choose the front, middle, or back of your side (which would either be the top or bottom of the map). This way, people as warriors can choose to spawn up front, but squishy mages can choose to spawn farther back. In addition, if you're, say, fighting a Void Assassin, they could choose front (to try to go for backstabs), but if you predict that, you can choose back (so they are no longer within reach).

EDIT: Also, a "random" option that is chosen by default, that chooses between the three.
