contenders season 1 here or here
contenders season 0 its more rare now again coz his blade is weaker and he rarely has nanoboost coz no one playes ana and nano is weaker but it happens
and why do you think genji players changed their playstyle? sdb could be more agressive year ago for obvieus reasons (which i mentioned) and are all due to meta and hero changes:
ana had op healing, able to heal even triple tank team alone so keeping genji alive when ulting, or healing him with nade when he was low was easy
nanoboost reduced damage taken plus you were faster, so it was really hard to kill nanoblading genji, not because teams didnt know how but because meta was different
so now let me ask you a question, during triple tank meta genji was pretty much not played (not like now more rarely but not played at all in pro matches) so back than teams really had to know how to counter him if he waas not played at all, so did teams forget how to counter him?
spoiler: no and again you really think teams need 2 years to adapt to something? np genji has multi kills with dragon blade when meta favors it (nanoblade meta) ut when it doesnt he wont (triple tank meta)
