What the hell happen ?

I was gone for since big bang and now all I see is disgust for the game as it is today. Fell out of it a little after the earth was formed to a habitable planet mostly cause I had no one to play with. With that said why does everyone here have a strong distain for the game as it is. I see a combo of balance patches, removal of solo (didn't even know that was a thing), unfair enemies, and class power creep. So what's up?
