welcome back dude!
19's went to shit. Even worse than when you left. more wanna be twinks with sub 1000 HP than every before. more pugs ending up with 5+ hunters or rogues than I can ever remember, less coordination
On a positive note there seems to be less mid farming, but that is mostly contributed to the bads not having enough HP to farm, they all die then run back to mid to do it all over again.
