So I Just Lost As The Jungler *****ing AGAIN

Now that the title has somewhat vented my rage - here's the last match from before this post:

I'm reaching the consensus from responses to a previous post (http://boards.na.leagueoflegends.com/en/c/tips-tricks/iY6ZdH9T-why-am-i-still-not-winning) that being jg is no longer a role from which I can carry a game. My playstyle is more "charge in, get punching", and getting myself or my team fed as a result, NOT "throw myself into a teamfight, hope my nearby but under-powered team can follow up".

I only gank for lanes when I see the opportunity to do so and I can get there in time, not when people keep pinging me to "help gank plz" after they fucking feed their fucking enemy laner. I'm in the top side of the map farming, they give Jinx a double kill on the other side. "Vi ur bad jg".

SO that leaves the question. I try to wait for opportunities, I don't force them unless I'm fed and wrecking them. If my team is losing, do I build tankier to peel for them, or do I continue building the damage item I was working on to try making the kill myself (building defensively only to mitigate my own suffering)?

That said, do I just stop jungling and try to learn an easy-middle difficulty solo laner who can farm, watch his/her own back and carry the team with damage or split pushing? Someone on par with the difficulty of Vi or Volibear or Sejuani - no Zeds, Lee Sins, or Rivens plz. I find ADC too dependent on the support's performance at times, didn't climb out of Bronze with that in S4.
