Quagmire, something seems wrong.

At least its down to 173 as it should be, assuming 173 is you with absolutely no buffs at all, save the items buff (as stated above)

I think the "not-cancelling-berserk" thing is probably done that way because technically Quagmire doesn't work like Dispell (which when coming into contact with Berserk cancels it and of course drops your aspd)

Quag is just doing its job of lowering ASpd, and whatever else it lowers.

Plus if you were berserked and close to death, you'd prefer Dispell to Quag (because Dispel cancels Berserk and leaves you with full health, whereas Quag would cancel the effect of berserk but leave you with dying health)

So Quagmire is actually a better choice strategically if considering Berserk.
