Honestly despite me wanting to buff astra too, she seems to be in a good state: the dome controller pickrates are largely similar to each other(viper is wall controller so she doesn't count). Brim dominates bind and fracture, breeze and icebox is viper maps, and omen and astra fights for the last 3 maps(2 if you exclude split, and no one knows the meta for pearl). Omen and astra are on equal footing on ascent and split with astra being picked more slightly. On haven, despite omen seeing far more picks than astra, astra has a far superior round win and map win rate % than omen.
Tldr: controllers are balanced(other than viper who honestly just needs another wall controller to be added) and pls stop asking for controller changes.
