It's not an automatically rotating cycle like TF's. She activates it once, it switches once, and she can do it as often as she wants as quickly as you can press the button until she uses an ability or attacks. And yes, they remain constantly locked in until she switches again, death will just retain which one she had when she respawns again.

The lack of burst takes into consideration the fact that she sustains it instead, which I guess if there aren't any straight up melee mages already, just means it a new thing.

Thanks for the comment though. I'll have a think about it.
