No. The breakpoints still exist, if you have enough alacrity rating you could run with a 1.3s GCD. It will be significantly different APM than at 1.4s GCD, i.e. it works just fine. The results were only to prove or disprove if GCD was being rounded to tenths or hundredths of a second. It’s rounding just like LIVE, up to tenths of a second.
