I agree to disagree. The most skillful of the skillful should many times fail in the right circumstances. And in a game, where is the challenge to a math path where the right choice always reaches the goal? The challenge comes from the unforeseeable events that can make or break, not from following step 1, then step 2, then step 99 until you reach your goal, if you don't forget about some important steps.Removal of skill variance is not skill, and claiming that removal of skill variance "adds challenge" is nonsense.
I can WC. bbqftw can WC. Marco can WC. There are clear jumps in game performance between us (I'm the least skillful). A game mechanic that makes me succeed where Marco fails by random chance is nonsense.
Is there fun in routine? And pardon me, it doesn't mean you are skilled if you know to follow a path. The skilled people are the people that know to deal with the unforeseeable challenges AND know when to accept defeat, not the ones that do the right thing when the roads are laid.
