Slightly buff it's DAMAGE. Nothing else. Like +30%. Maybe specifically versus heavies.
Snares are good vs lights, bad vs mediums and awful vs heavies. Main purpose of snares is to get veterancy. So at vet3 when there is nothing to get snares lose most of their value.
Now infantry is too weak versus tanks in late game. It should stay inferior but not close to being useless as now. Main purpose of late game infantry is to spot for AT and b a shield for it. They lose too much of their fighting value.
Obviously it shouldnt disballance anything since it would affect all factions same way.
