Orange Box was a great package, but I experience the same with TF. Technicalities aside, I didn't find the game fun -nor I am very interested in Overwatch, despite being a Blizzard fan for years, and having all the Diablo games since 2, console version included, although I play those games on PC, and StarCraft 1 and 2-. Never got into TF, despite the fact I was hyped to play it because people kept saying very good things about it. Tried the medic overall, maybe it wasn't my thing to put injections, but also the engineer didn't seem very fun to me. Dunno, maybe it's one of those games you really have to get into to enjoy it, or whateverI never found TF to be a fun game. It's probably the same reason (class types) that I didn't care for Overwatch either.
However, that downgrade would be make Ubisoft shed a tear....
