I mean we got kinda Bad Xpac(BFA) and then we got hit wit SL and bro... SL was really bad it was the first xpac since i started playing in WOLTK that i skipped 1 major patch completely(9.2).
People got really sad/angry with game and general negativity started to go wild, i'm kind of "I'll always have faith" guy, so i hoped DF would be good and for me and many of my friends it has been really good, of course there are problems, but it was a step in a good direction.
It is really hard to build faith/trust in something, but it only need some grave mistakes to make it all crumble.
