Hum, I've no problem with the MCH, even with my 80+ ms of ping.
And I love the way they redesigned it, except I miss some reloading animation (such a shame they deleted it) and some supports like Mana regen or vulne on foes.
And I wish they'll give MCH and BRD more aoe, it's kinda boring in dj. Even if the MCH isn't that boring.
But +1 for a buff.
