Ever been in Goon Haven or aloha pinpoint, or any map which has lots of water? The ones where half of the enemy team just goes out in the water? Especially when they're far off, they're pretty damn difficult to hit, because only a bit of their head sticks out, while they can see our entire bodies. My suggestion is that when a player is crouching in the water, they're at least a little bit more visible to players on land, because I find that 1/5 of my shots miss the watercamper, while they can get a clear shot on me easily.
Discuss.
