A lot of my fear comes from lack of practice actually. I've jungled once in Nemesis draft, and did ok (
) but while I like jungling I feel like there's so many aspects of it which I don't have any form of practice with. Mostly the ones stemming from lack of an opponent jungler.
I also lack good practice with playing solo top for the same reason. Meaning the few times I feel up for PvP I either play support or a lackluster top.
I guess some of it can be solved by good enough guides (I have no idea how to roam as mid for another example), but there's no good substitute for real play.
Heck, I'd take a few good mocked up tutorials, pre-defined but slightly randomized scenarios, that teach you stuff like what happens when you get counterjungled at your first red or how dangerous it is to go into the opponents' jungle to try and steal something.
Or opportune moments for a mid to roam.
It's stuff you currently more or less just have to pick up somehow, but I'm sure there's lots of people who do better when they have something explained to them in detail, or who don't learn well under pressure.
Note, bots harder than intermediate would be challenging to beat, at least for a while. Just as Dominion/TT intermediate bots can be more difficult because of the more focused maps.
I think it'd be easier to bridge the gap to PvP play for those who for some reason feel they might not be good enough to keep up with their team.
Or rather, weigh their team down.
Whether or not those fears have any good reason to be there or not.
