mmmmm now you have another problem if a player rolls a 1 as any of their stats. They can't succeed. But that might be "by design" (poor PCs)
Yes, it’s by design.
It’s rather a better “balance” that a character be bad enough at something to not be able to do it than it is to be awesome and never fail.
With an Acrobatics of 1 a player will still be adept enough to run, roll and jump as normal, but trying to pirouette on a balance beam is always going to be a failure.
