Nope there are light only areas but all the objectives are all where any bodytype can reach.
Thank god. I was worried about that..... what would be the benefit for lights if anyone can reach those areas?
But anyhow, I don't like the HORSE idea as it applies to Brink but I think the "Parkour this" is the closest your going to get.
I would do it like you can issue a challenge to another light player (either side, I guess) during a game where if you can perform a combo of moves then you get some sort of temporary bonus.... but even then it would distract players from the mission at hand so no.... nevermind.
Besides, I think there are a set number of mission types like escort, defend, destroy, etc. and any future maps would just be variations on those same mission types.... unless they can dream up a new and innovative mission type!
