This champion leaves 0 counterplay. Rengar has ! mark, evelynn has a radius that you are revealed. Yet shaco, champion that can oneshot anyone at level 2 or 3 can be invisible and nothing can be done unless you have a pink ward which is impossible to have especially in early game unless you like to start as mid laner/top laner with pink ward and 4 health pots or as a jungler without a jungle item. Make his Q give a warning as eve or rengar does. His burst is too high to have invisibility that doesnt give a single counterplay option.
