It always goes like this with kids:
If you're gold - "Wow you're only gold? NOOB"
if you're plat - "Pff, only plat?"
if you're diamond - "Diamond in EUNE doesn't count"
if you're diamond in any other region - "You suck because you're only diamond in *literally any region*"
Meanwhile the one shittalking couldn't make it past the gold promos, whatever I do I suck, if I was challenger in korea I would suck because I did it with only 50 ping or something.
Yes I'm diamond, yes I'm a good player, no I don't suck and yes diamond in any region is a great achievement.
