Well, if that’s the perception. There’s also a potential roll as spotter/scout
I would invite you to try my modmod; it includes that formation change we discussed as well. I think a conversation would be more productive if you had a first-hand impression of it.
with 5 moves, regardless of terrain, there is no situation where a skirmisher can’t move at least as far as a horseman, with or without the movement penalty. If people don’t like horses moving through 3 rough tiles in 1 turn, then 5 with rough is the fix.
I don’t think it is worth the weird interactions with certain civs’ movement bonuses (Inca, Songhai, iroquois), and I don’t like the interaction with certain UUs (Berber), but I can live with it if moves is increased to 5. I do think RCS numbers need to be lowered, and CS numbers raised, regardless of all else. As I have pointed out, skirmisher line CS fluctuates massively in respect to their contemporary units, and much of the hate levelled at later eras units could be explained by how easily they die.
