aurora can win in small number vs other tanks if microed do dodge every shot by wiggling
Thanks for your input Turin. In case it wasn't clear, I'm a little more concerned about more average players than yourself (who often struggle to micro effectively and keep up with everything else). Of course it's an open question whether balance should reflect only on the top players (this seems to be Jagged's opinion if I understand correctly) or whether lower-ranked players should be considered (this does have a caveat: under-representation of Aeon at lower ranks may in part be because new players who do well with Aeon advance more quickly than with other factions — but this is pure hypothesis without evidence).
Aurora are quite strong
Well, yes. My point above is that they are too strong in large numbers and too weak individually (though Turin clearly disagrees with this part).
