@Sprouto Setons is the only map where typically all share is considered standard meta. All other maps simply dispose of lost player units.
This current freeze could allow a self sacrifice of one player to ensure the fighter/bomber snipe effectiveness of another. If chances are good of getting 2 snipes after the initial hit and resource passing has been involved in speeding up the fighter producing players eco, then this is extremely exploitable and bad for fair gameplay.
There's a few other extremely important handling things that go on late game (nuke avoidance ect...) that has been adversely affected by this change. Desync problems mostly are you catering to people using wood-league computers anyway, so stop sweating their problems, just tell them to get do some part time work and get a new rig.
