I would like ladders if ranged wasn't so prevalent in the game. They add a tactical element and make the maps more dynamic. Putting a ladder down could change the whole way the map is played, and then the next time you play the same map the ladder won't be there or the ladders will be somewhere else
Ranged spoiled ladders though. Can't have nice things when people use them to get into areas that allow them to pewpew all round from safety
