Put this in perspective with the new Monk Buff. Howling Fists is a 40 Potency increase a minute, and Demolish is a 20 * 10 * 1.3 * 1.1 Potency increase per Minute, or 286 Potency increase a minute. So Monks got a 5 X Potency Buff increase per Minute over MCH if you don't account for the Pet.
I personally like where MCH is at the moment, but their big buffs were the QoL changes to the Flashing Skills IMHO.
Edit : forgot to take into account Gauss Barrel, so 1.3 X 60 is 78 Potency.
