I'm not sure if the skills are unsynergetic, to be honest. You can not have all buffs and debuffs at the same time, but you aren't really meant to. If you have about 2.0 attack speed (compare: Jax + Trinity Force + old Rageblade with max stacks had 1.9, and their passive steroids are about equal, Jax a slight bit stronger), you get one second cooldowns reduced per second of battle, which means the cooldowns are half what they appear to be. So 3, 3 and 3.5 seconds. You'll constantly be applying new debuffs etc.

I do think that, even though you'll never really miss out Sheen procs etc, that you can't faceroll her, as I imagine her ultimate autoattacks to be really difficult, as you are at the other side of a champion after every one, almost like you're dashing. And this means that you can't always switch targets, but if you do it correctly, you can "dance" through the enemy team to the carries.

About the physical DoT, I had created this champion around the first Season 3 patch, I think before the Item Overhaul went live, but after it was on the Public Beta. Back then, we didn't really know the power of Black Cleaver, it might indeed be a good one to change that, mostly if you note it can be applied every 3.5 seconds and the DoT lasts three seconds.
