Hey there Hudson. Yes I am aware that solo laners are generally always going to be ahead of anyone else in xp. The thing about the jungle xp disparity is this: while they hit harder, give more gold and xp, there isn't enough time to stay even close to even with laners. The long spawn timers, and necessity of buying pots ensures that you won't have much gold. The same goes for experience: the current iteration of the jungle works in theory, but only in theory. Any attempt to leave the jungle to try to influence the game is really risky because you're just always behind and failure means being even more behind.
So anyway unit for unit, YES, jungle camps are worth more xp and gold than creeps, and that is as it should be. But over time there is currently FAR more gold available to laners and while I believe that there should be more in lane than the jungle (which was always my problem with feral flare: less game interaction is rewarded with more gold), I don't believe the disparity should be this vast. Furthermore, people want ganks, they are an important part of laning phase. But the risk/reward ratio is currently so stacked against junglers that it's just frustrating as hell. You want to gank, but you're too low from doing the past few camps. You want to gank but you know that you'll probably just burn flash and meanwhile you're losing valuable xp and gold. You want to gank but you don't have any power from items so you're dueling potential, already low due to being 2 levels behind your target, is really low.
Anyway, I don't disagree with you in theory, but in practice, junglers are currently very low impact and always broke and it's just not fun. In my opinion the junglers need either to have their gold passives back on their items (conservation) so they have an incentive to gank without losing gold, or to just make the camps worth more/spawn faster. Beyond that, there NEEDS to be some sort of sustain option in the jungle. I really hate only being able to choose one of like three or four jungle champs, 2 or 3 of which will get banned anyway.
