Xp System?

[Window Licker 504]

Yes, but no.

Not an MMO style level-up with unlocking new skills, but rather a hidden xp system that allows you to develop your survivor's skills.

For example, repeated use of bandages will result in quicker application of bandages and possibly the use of less bandages (10% instead of 25%, maybe.)

A system like this has already been confirmed by Dean himself.

Indeed it has, although for what skills and how they are affected it has not been spoken of recently, it's likely something they will slip in near the end of alpha. So don't hold your breath, well you can try just do it laying down.
