Stop playing then. I stop playing ranked if I lose 2 out of my last 3 games, solely because continuous losses can make you go on tilt faster, which increases the likelihood of losing more games. I also stop when I win one really good game, cause I want to bask in it's magnificence, and I don't want the pressure to repeat it.

Hence why I have yet to play 100 games of ranked over 3 seasons :> maybe I'll break 50 by the end of this one.

I only installed league after S4 started and I've played 345 games.

God I'm so hungry to be good and its just..not..happening man

I think I'm pretty good. I just need better internet and a new PC (mine is 9 years old).

900 ranked games in the last 2 seasonsand i'm only gold 4, i know that feel

Why are we so bad? Why are we not improving?

because you're playing more than you're learning

Do you watch pro streams, videos etc?
I don't consider myself at all good, but I have improved so much just through watching other people play and learning from them XD
Professional matches are good (LCS games etc), but you don't get the same detail as you do in streams.

Braum's lore @.@ manliest man ever. Punches through mountains and doesn't afraid of anything.

Because you're rushing it. I have said it countless times now, you need to play a whole lot of normals first. Believe it or not, you're still considered fairly new to the game, no matter how much you deny that. I started playing early season 2, but my first ranked game was in late season 3. You can say a year and a half after I first started playing the game.

Started bronze 3, got myself up to plat 5 before the season ended (around 4 months of playing ranked). Whenever I lose 2-3 ranked games a day, I just stop playing ranked for that day.

Point is, stop being so impatient about it. Completely stop playing ranked, play normals until your fingers bleed, expand your champion pool, be considered decent at all 5 roles (and no, stomping in 2-3 games does not necessarily mean you're good at that role), practice practice practice. You need to be much more patient.

wtf
if you wanna be fucking good at this game u pick a champ u enjoy and u play the shit out of that champ
doesnt matter in ranked or normals

ranked u actually have to group and try to win
js

after ur done u expand on that, such as me playing riven EVERY game and expanding into more mobile champions like renekton or tryndamere
