I'm dead set against them getting swamp survival. I don't see why they should. They aren't swamp dwelling races. If it's on the basis of them being amphibious, why not give all amphibians swamp survival?

It came from thinking if it would be possible to have Ichtycentaurs run on water, i.e. sailing for Ichtycentaurs lead by Ichtycentaurs. I realized the current Sailing command wouldn't work and implementing another mechanic would be a huge process at this point, so I didn't even mention it in my post.
Then, from that, I thought that at the very least they should be able to do that on swamps. I liked the mechanical effect it would give them, so I suggested Swamp Survival.
