I usually like giving people the benefit of the doubt, but TF2 makes hundreds of millions of dollars a year. I could go on for literally hours about the plethora of issues and major fuck ups that have hurt this game for a decade, but they've been discussed to death already.
Normally I would say, "Oh they're human, they make mistakes," but when they make gobs and gobs of cash from this game, it's just not justifiable.
CSGO is similar as well. It takes a special kind of retard to add an $800 pistol that outclasses the $5000 sniper in every single way. And people always defend valve by saying it got fixed, but forget that it should never have happened in the first place.
This is valve's business model now, have a game that makes a shitload of cash, then do the absolute minimum of upkeep. The only reason Dota gets better treatment is because they have IceFrog, who's made his life about improving dota.
And don't forget that these issues with TF2 have been going on for almost a decade now. The jarate is fundamentally broken and will never work in a competitive envrionment. Also, why did they add a jar of urine into this 1960's industrial era, spy vs. spy themed game? WHY A JAR OF URINE? JUST WHY
