i get taxed all the time when you fail your gank, i deal with it. please just stop raging about your 1 bad game where this was an issue which should've been prevented by your communication.
i would share my lane gold and exp if it meant a better chance at winning. but it doesn't. its proven that laners with more gold and exp do better than a jungler with lots of gold and exp.
what actually wins games is 1 person snowballing and 1 person on the enemy team super behind. preferably the mid laner, but anyone can make it work.
you aren't as important as you think you are. im a mid/jungle, i would know. i can take all the kills as a jungle, cover multiple waves and will still be behind in gold and exp from when i was a mid laner doing the exact same thing. its just how gold works.
you have about 3/5ths gold compared to what a laner has, you missing some or gaining a little more isn't a big deal. you are majorly supposed to function off of levels and placement/player number advantage. otherwise you would be in your own lane because lanes naturally give more exp and gold
what you are really experiencing is bad team mates, and losses at champion select.
i would love it if you showed me 10 screen shots of "damage dealt to champions" where you are ahead of everyone else and how important it is for you to have all the gold in the world and not your laners.
