In the last 10 years I've put so much time into TF2 that it's hard for me to actually fathom.
And money...
Sadly, the day Overwatch released and I tried it, I instantly fell out of love with TF2. Something switched in my head. I had forgotten what a game with a loving, focused, attentive developer looked like. TF2 is frayed on all edges, replete with gray hairs and wrinkles, and although very much still alive, a shell of what it used to be. To me and to many many others.
I wish you the best with TF2, it is capable of some truly wonderful and satisfying experiences.
