Now, to get this out of the way, I'd sooner KEEP the snare and nerf them otherwise. I have always been alone on that boat but I'm going to proceed with this question anyways:
Why would removing their snare REQUIRE something else in exchange? They are OP because of a series of buffs. Why does creating a weakness (which they currently lack, thus making them OP) require some sort of counter buff? Is camo, first strike and good at all ranges not good enough? What if they also fucked shit up on the move? How about a bundled nade? How about poison smoke to negate CQB squads and allow them to recloak for that ambush bonus again? Why do they NEED something given back if something is removed to BALANCE them?
I would just revert their DPS changes and tie them behind late vet and keep their ambush bonus rework exactly where it is. They can earn being fuck everything everywhere at every range, but until then they need to be used as ambush troops. Keeps em unique (even though "use in a specific way and not just attack head on regardless of terrain" isn't really OKW's style it was always nice that falls were outside the norm.
it's ok to create a weaknees with no counetr buff if the unit is OP , like the jackson, but falls are barley used as tournament and quick match
