Does anyone want to engage with the question I actually posed. Yes there are the abilities and units in the game to deal with blobs. Thanks everyone for pointing that out. That's not what I was asking. I wanted to know if anyone recalls piospam and if a penalty for clumping the same types of units together would encourage a more diverse style of play for the vast majority of players.
nah. occasional blobbing is a good tactic. what if you have 3 units together along a line to take advantage of green cover? i think that solution is too artificial and will do more harm than good.
