I don't think you quite understand the meaning of "skill". I believe we have we over this before.
A mouse can have skill. A goldfish can have skill. A dog can have skill. Skill is learned. That is all it is. Nothing more than that. It is nothing special.
Some people may be better because they are faster or quicker. Being quick/fast is a natural ability. It can be enhanced with practice.
In this case, it would prove what team(s) could adapt faster to the new prepatch. More than likely we won't have to worry about it.
However, having a contingency plan is always a good idea. Trust me, you always want to have a Plan B in practically everything you do. Someday, when you most need it, it will be there and you will be glad you took the extra time to make it.
You are correct it is 4-6 weeks before release. But when I warned them 8-12 weeks ago we did not know exactly when release was going to happen. And the TC is going to barely make it, maybe...
