What do you mean by "performance"? An all around debuff of 20% on everything?
20 meters is quite a huge distance. Think about a whole 40 meters of space that can't / shouldn't have a second infantry squad nearby - impossible on some maps, really bad for lots of compositions.
If you retreat, and multiple squads are in the same area, what happens then?
Hi Kamk,
For "performance" I mean: damage, accuracy, speed...
I wrote 15 to 20 meters, but is just one example ... could be 4-6 meters. The goal is to discourage the blob tactic.
When you have 5 squads and retreats two squads (for example) the "damage, accuracy, speed..." of single squad improves... from 41% to 64%, see the image below (green line). The cost under the green line suggests that the cost of a Blob 5 units (for example) is 1250 MP, but is efficient as units that cost 512 MP ... and this is not convenient.
I think that in this way no one would blob larger than 2/3 squads ...
