Hey,
You are showing a extreme case of not even smurfing but someone deliberately screwing matches over so he remains at a certain rating.
Someone who actually "smurfs" will try-hard and climb up as fast as possible.
I'm going up and down diamond 3-4 on my main account and i can promise you that for me the only way to climb is to try my best every game and even then, it's not guaranteed that i'll climb outside of diamond.
It's quite stressful from time to time and i normally don't grind ranked games.
Had a old account lying around that i never really used and went from unranked to Diamond 5 within 60 games.
Just to see if i played champions i don't play on my main account i'd be able to carry/perform well and to experience the "elo hell bs" you see on the forums every day.
Sure, had a few people upset that i was smurfing. Funny enough you won't hear them complain when they get blatantly carried by someone else.
My point being, i played 60 games and over half of that was reasonably close to my main accounts elo (mid plat - low diamond wont complain if they have a diamond 3 player with or against them)
so i "decided" 30 games at a rating i could truly say i was smurfing. I didn't feed/troll/rage or do anything even remotely toxic. All chat disabled and i barely use the teamchat anyways.
Do you really think its that bad? just wondering.
Best Regards,
Dushi
