I refrain from suggesting such changes because I've been told Relic is very clear on not making big changes to UKF, so I focus more on small changes like removing the cover bonus. Not saying your idea is wrong, just probably not allowed to be implemented by Relic.
Imo the introduction of the officer and cover changes where allot bigger but that is just me.
Funny thing is that I did pointed out that the combination of cover bonus and ability like assault and advance cover bonus where recipes for problems.
Another issue is that Tommies once upgunned again get bad DPS since the bren does not fire on the move. That can be even seen in the tournament since allot of people did not even bothered with brens as far I saw.
