The Cover Change Alone Is The Best Change
Honestly, if you guys liked the old cover then you need to go get your brain checked. No one liked only being able to remove 2 hits, 3 hits maximum when a clone player is throwing a fistful of black dice at you. Cover actually does something now and better emulates the movement of an actual combat; Infantry is ducking and scooting across cover as they are being shot, and this better simulates that active combat environment.
Any and all real life combat scenarios are about getting small or getting covered in order to fight the enemy. No on wants to be zerg rushing across open ground in the vain hope that their enemy is just going to miss them. We all get a free ward save just for being smart and using cover to our advantage now, and units are less likely to get blapped out of existence.
