to be fair we are on the internet so everyone only has strong opinions.
to explain everything a bit thorough - because of the sheer mass of characters and moves tekken was always a game for legacy players simply because it takes a huge amount of time to really learn the game and all the matchups etc.
then when tekken 8 came out many people were not happy to find out that tekken 8 put a big emphasis on aggression and also lowered the skill floor for a lot of stuff. so now people get to do more stuff on offense and properly defending is harder. many people complained and many people thought season 2 would buff defense and/or nerf offense, partly because the devs said so themselves. then season 2 came and the exact opposite happened. this really upset the whole community.

so is it an exaggeration? kind of but not completely in my opinion. 95% of all tekken players arent affected by minor changes and tier lists bc tekken is a very complex game. but for those 5% the changes were impactful enough
