How come I keep losing?

You didn't feed in one normal game as urgot and instantly took him to ranked. What'd you expect?

while I wasn't in the games in question to say specifically what went wrong, just looking at your match history kinda says its on you. Most of your losses your kda is very deeply negative. You also play champs like that for the most part are immobile and/or don't have much impact on the game until late game.

With games ending faster and faster now with buffs to AD and crit items, late game champs are becoming less and less viable imo. That's not to say you cant play a late game champ, but if you're entire team for example doesn't have any real kill pressure or map control until late game, then you've already lost. Try to get better at / pick some more well rounded champions in regard to their strong/weak points. For mid I would suggest as they can be relevant even if they are a bit behind, due to their ults and/or CC

for top I would recommend juggernauts mostly, my personal favorite is but are also solid picks because of their strong early and mid game, most of these champions fall off late game but not so much that they become irrelevant.
