Why was the decision made to make it so mines don't 1 shot a super light? Should mines not 1 shot kubels, m3a1s and UCs? You invest 30 muni into a trap that your opponent knows could exist and they don't get punished for it is pretty dumb.
Best I can tell, 1 mistake total punishment is pretty miserable, especially before sweepers are reasonably available. The M3A1 should have almost instantly died to the SPs.
The M3A1 is a weird Ultra Light, being the heaviest of the class and also the most expensive. Almost the lightest LV. A signature of the Ultra Lights was not hampering teching due to not costing Fuel, so losing one sacrifices Map Presence instead of raw tech timing.
The UC is the only exception, and that's pretty dang recent.
I can see why they made that change, as before a reasonable expectation of sweepers, mines become a lotto for just ending the early game pressure entirely and massively putting SOV behind. SOV generally opens Flamer, and can't stack sweepers and Flamer like SP.
Tellers are fine because by the time they are out, SOV players should have the second CE squad with sweepers out.
The current state seems fine. If we wanted to revert it, I'd suggest let CEs stack Flamers and Sweepers.
