Actually, I think the minimums now encourage the fatigue strategy for those that have the time... the fatigue system still works the same, and now there is a requirement to draft more PA and IP than needed (especially with AAA), other than time factors, why would someone not run a fatigue team now to account for the extra PA and IP requirements, if even only on a smaller scale?
And if you get used to running it on a small scale, why not try it full scale? This doesn't prevent fatigue teams at all, just makes it a little less intuitive for those that haven't tried them...But since it also encourages them to be tried, at least on a small scale, it shouldn't be long before more people are accustomed to using such teams.
