I didn't feel like there was any celebration at all. It was just a few weeks of trying to grind out new skins with very little luck. None of the old modes, none of the old events. It was a sad excuse for an Anniversary event.
Also, I play about 6-8 hours a day and run into hackers almost daily. It is so common in fact, that I'm reporting someone with video proof just about every day now, with no doubts about them being a hacker. Even their team will mention it most of the time.
One common hack I've seen the last few weeks is someone being able to regain health at a nonstop fast rate, with no healers on their team, and no health packs anywhere near them. Just, they hit either half or quarter health, and their health jumps back up to full, and then they don't take damage for a couple seconds from anything.
