Opinion: Sometimes we think we are better than we actually are
I'm sure we've all seen the Bronze and Iron compilations by Solo Feed. Obviously, I don't know how high elo you peeps who are reading this post, but I would say that most of us wouldn't be making the same mistakes as the people in the compilations would. But still, when I play, sometimes I would see so and so person make a mistake and depending on how big/what the mistake is, my reaction internally will be something similar to WHAT THE FUCK ARE YOU DOING. However, if you look over your own VODs in some games, occasionally, you do some dumb shit mistakes too. Obviously the frequency of such mistakes or how terrible these mistakes are depends on your elo, but i think looking in your own perspective at others' play can sometimes be warped. Obviously this doesn't apply to circumstances such as bad matchmaking (a whole elo separated or boosted people), trolling, inting and MMR, but normal games.
This could be just me, but have you ever made a play and immediately thought afterwards: "why did I do that, that was some dumb shit" ? And you know if you saw someone make a similar mistake, you would probably mental boom or facepalm hard. I recognize that I am probably a lot worse than most people on the boards, but I feel such mentality can apply to higher elos as well, not just low elos.
BTW, this is in no way any flame to anybody, and i'm not saying to completely put the blame on yourself either, because I don't think that's a healthy mindset either. I just encourage people to think from another perspective and sometimes do self-reflection when time/situations call for it, because it was something that did help my playing experience in the current state of league.
I AM PERFECTION!
