Tbh that wouldn't necessarily be a bad thing.
If the power bump came from 7 man instead of the T70 we might see some su76s or quads out and about instead of just the T70. Power bump is still a power bump so idk if it needs to come from the T70 specifically.
However a sooner 7 man would need maybe for the mp reduction to be delayed till t4 possibly but it's something Tha could be played with
I would gladly sacrifice T-70 to get 7th con faster, but I don't know if game and forums could withstand so many buttholes being raptured at the same time if they would see that cons actually get combat upgrades at similar timing other infantry does.
Its one of these things that will probably just be status quo for life.
