The problem I see here is that this kit is literally unplayable until you put a point in Q. Every other ability is completely dependent on the presence of a geomark: aside from forcing a skill level order early (as well as leaving the possibility of a completely unusable kit), it also risks creating an extremely binary fight pattern: if you've got a geomark on your target, you can execute your full combo on them, but if you don't, there's nothing you can do until your Q or ultimate comes off cooldown. The rest of your kit is fine, but I would advise reimplementing the geomark mechanic as a passive. You don't necessarily have to change your Q, you just need to allow your champion to lay down geomarks without being fully dependent on that skill.
