TristanIgnoring the fact that 6s evolved from a ruleset similar to the one above, it seems like you'd see more variation in play style with 1 of each class. One reason for this is that everyone would always run 2 demos with the other rule set.
All you would see is more turtling caused by lack of combat lasses and almost guaranteed constant presence of heavy.
Imaging trying to push off last without switching back to main classes....Except the other team is also running turtle classes...
