If you revert Tommies you'll get the old Bolster Swarm back.
UKF needs buffs to units that support its Sections or it'll just snap back to the infantry spam faction it was after SBP.
Bolster needs to be changed to not be a low risk high reward global upgrade.
Tommies need their burst damage back. In my tests of Tommies in green cover vs sturms closing across no cover the only time they won was when they were able to drop 2 Sturm models before they closed and that was 1/10 times across no cover head on into ideal condition Tommies.
Bolster needs to be a choice that has trade offs, like it is for the other units capable of such a feat in order to both have it viable and competitive as well has not having it being the same
