I feel like a full foot between objectives, especially with the increased deployment area, means that objectives will be very difficult to place.
I'm also uncertain why any player would choose to pick a unit for Corrupted Planets - the rules say, "may" instead of 'must' and the only potential outcomes are unchanged or bad. This is doubly true if the unit has the Undead or Robot rule. Additionally, if a unit is already Shaken there is no reason not to choose it - there is no possible negative effect.
