I agree, there's a lot of champions out there:, , , , , , , , , , (he USED to, yes still bitter),  and. These all use some form of "Marking", "Consuming Mark" or "Mark Stacking" and in every single one they provide bonus effects but never do they unhinge an entire kit if the stack is not there.

The closest champions that don't really function without their marks are and  who kind of need their DoT ability to be on in order to deal damage reliably. I do applaud the attempt though, as there's potential. Try to go trough the listed champions and see if you get any inspiration to improving your concept.

And a different tip: your Q does too much and get's over complicated due to that.
