With RoS, Time Compression was entirely changed. It's now an ADC buff and an increase to profession spells. Ancient Fury adds ticks. TC's restriction in regard to Ancient Fury - AF is suspended if TC is active - should be re-evaluated (and IMHO removed). Upbeat tempo adds ticks and cast/reuse/recovery haste. The restrictions of Time Compression in regard to Upbeat Tempo should be re-evaluated (and IMHO removed).
