I was on the edge of my seat every time we went into a teamfight. It was amazing. Why can't most of my game be like that?

Parceval1 votesPersonally, I believe it's because their matchmaking system is very poor.
From all the indicators I've seen, it looks like they're starting to make intelligent strides toward improving that system. Notably, having a new team builder implemented that allows them to properly match on a role by role basis. Thusly they can better annotate, collate, and execute on data they collect from that first premise.
For now, however, their matchmaking system is just simply bad. Ergo, 49.5% of your games are heavily tilted toward loss, 49.5% heavily toward win, and the other 1% you have a measurable impact. Of course, those numbers are purely opinion.
EDIT: I just clicked on your links, 10/10 troll?
Z Statistic1 votes? No idea what you're talking about.
First link is of both teams being within 2k gold of each other for the first 30 minutes and then my team exploding after a good play. The second link is of my team getting a small lead early on and then exploding at 15 minutes.
