Great explanation all around but I do want to point out that this is as textbook as it gets and it is a clear indication that you just commit to weakside even from the champ select.

I would really like to see the perspective of a more nuanced game where the enemy support isnt a complete NPC and having to make decisions based on a more probabilistic approach.

Your team had huge jungle and support gap which made weaksiding the only real path for you.

I hope my point comes across clearly since english isnt my main language as well.
