if a yellow trinket comes up every 120 seconds thats 2 minutes. you average 12 wards for approaching 48 minutes, which is one per four minutes. giving credit on the free pink ward upgrade at least but even then leaves a lot wide open.
this is accentuated by the fact that the enemy jungle was evelynn. while a pink is required to catch her in stealth, multiple and agressively placed normal wards can and often do spot her out of stealth giving a tip off on general area.
i am going to further say you may think you warded a "lot" but you didn't even ward to the full potential of a yellow trinket.
further you were third place on your team for warding with less than half of the others vision generation.(support 31, mid 26, you 12.)
so you lost and got "cancer" by existing in a fantasy instead of reality even in review of the facts.
we are all terrible a lot of the time, but ignoring the reality when it is there in black and white to help us see how we failed, means we never fix it or even try to. this divide with the vision help is clear in black and white. you DID NOT ward a lot. or enough even when it was free.
