You ought to buy more vision mate. You play around Gold, which means people are most likely never gonna buy any fucking wards and even if they do it's typically only 1 during the laning phase.
You placed a total of 3 wards during the entirety of the game, which is low even by Gold jungler standards. Now, you were also very fed right from the start, which means that you should've snowballed your other lanes or helped them out from being behind. Being a fed Kha also means that you alone could've snowballed the match into dust, as you outleveled the enemy Heca in early game and had a solid 3k gold lead on him at one point.
You could've carried that game easily, seeing as no one in your team really "fed". The enemy seems to have been simply better at taking objectives and rolling with their lead.
You live and you learn mate - don't make the mistake of blaming everything on the team like most of my friends do. :V
