Repel is broken.

[Sombre]

Well the bug can be mitigated to an extent by making dragonflies non mindless.

I'm definitely not saying it isn't bugged. I think the fact that it works differently with mindless units isn't what the devs intended and doesn't make much sense. I just want the thread to be clear about exactly what's wrong with repel, why it should work differently and what could be done to fix or change it.

I always regarded swarm as an army delaying spell rather than an anti SC or anti assassin spell. The dragonflies suiciding themselves against a single sword doesn't seem right in any scenario though.
