Why nerf one thing, when you can just revert old building time nerfs from soviet t1 an t2 units, so instead of giving soviets back that annoying monopoly of early map capping you force both players into fielding support for their cheap infantry?
Because building time is irrelevant if you do not have resources to build anything?
Soviets are not meant to slap a tier at the start of the game, if they were, their tech would cost half as much mp and required quarter as long build time.
Going any tier at start severely diminishes your early map control due to mp starvation.
You basically can NOT afford NOT to go 3 cons 2 CEs vs ost anymore.
