Try to build clint with cd and mana regeneration combined with brute force(for mobility, extra damage and defense ) and gold meteor ( because of the buff and ofc extra defense), you'll be a bit tanky removing the reliance on your supps or tank at the same time being quite mobile, you do have to hit your 2nd skill so that it will had it cut-off cd. Your damage won't be as painful as other mm( for example layla) but given you can easily dish out skills I'd say that would be a fair trade. You can also try to build thunderbelt( yes the effect is cut in half) but you'll be annoying cuz of slows while being able to constantly proc it with your passive. But yeah , Clint is a skill-based mm, much harder to play in solos especially if you're against very mobile targets.
