You're overthinking those signs dude.
What do you mean? If a sign shows me that a route goes to x, I'll follow the route if I have a reason to go to x and avoid the route if I don't have a reason to go to x. If I play Pyro I tend to avoid doorways marked 'battlement', and if I played Heavy and came across a doorway marked as a flank route I'd probably skip it and go look for 'control point' signs instead. Are normal players expected to follow the alluring glow of any sign they come across, no matter what it says?

Started working on misc item for the heavy as part of learning blender better. Needs more tweaking and experimenting with bones.
