Judging champions

Hey there everyone so for the longest time ever i hated anyone that played aatrox or kha zix because i thought of them bieng very weak and i always judged my teammates when they picked those champions well the thing is this trend started for me after playing a long time with my buddy who was a aatrox main and is still in bronze 5 while playing over a thousand games of aatrox and whenever i smurf the noobs on my team are always playing kha zix making me hate him a lot. Last weak aatrox was free and i decided to try him out on my smurf account and saw he was pretty good so i ended up playing 5 aatrox games and i have to say im going to start shutting my mouth about aatrox he is a very strong champion if played correctly and kha i started to play on my lvl 1 account and i have to say there both very fun and now i have a lot of respect for the people who pick those champions.
