I fully agree with every word you said except the word "bad". A behind Shaco is pretty bad, i'll admit, but even he can usually capitalize on something. Anyways, my point: Shaco doesn't require an early invade, and actually farms pretty decently if he chooses to ignore lanes, he just isn't as good if he isn't snowballing. The reason I do cheeky stuff is because of the rewards for taking the risk. With Shyv, if everything aligns and I invade, I'm almost undoubtedly getting her buff and if she's there it's flash too unless her team sets up a trap without any of the early wards seeing any of it (unlikely). If shyv isn't there, I still get the buff and start ganking between camps. However, if i ever kill Shyv early, I can just continually camp mid and alternate where I mess with the shyv. For instance, if I get Shyv's flash at her 1st buff and get the buff, I just clear it, and gank mid (where I've had my mid playing passively so the wave isn't pushed and the enemy has to walk up to farm), then go straight to shyv's other buff and get that one too, as I prefer to get their raptors if she didn't go straight there and then get her from behind, allowing me to safely wait until the opportune moment. I may even be able to kill her if she decides to fight me after I take it. Shaco stays pretty healthy doing all of this except for the gank, which has potential to hurt. If it does, I just recall and head top jg to top and maintain control of her 1st buff. Once I get tiamat (I personally upgrade smite and rush tiamat) I can clear really fast and burst decently. If I get 2 kills by the time I get tiamat I'm golden. Shyv won't be able to farm very well (I like to keep warded and punish such attempts on devourer shyv) and ganks get fun. This is all conditional, but that's my big point. If Shaco is good enough to get the desired condition, and he knows what to do with it, he can shut out the enemy jungler or a lane or multiple enemies if he can get going. If he can get an early lead, he's a superb counter-jungler that's hard to catch out and easy to get ambushed by. As a Shaco sub-main (he's one of my top 3) I felt the need to justify him.
