I've been playing a bit more, the game has been a little bit better, but it's still not great.
Losing the second tank is still hurting everything and the changes made apparently in response to double shield which... only exist in OW2 which can't have double shield... are hurting the game. Insta gib is the new meta, and I can't really tell if they will address it because I haven't seen word one about it. Insta gib is basically dual dps that can instantly kill your players, so Widow, Hanzo, Sojourn 67. The problem is in dual tank comp, widow and hanzo had to contend with dual shield or a diving tank, so they needed that one shot power... because of Hanzos lack of unique angles like Widow, he got storm arrow which is mainly for shield breaking. And sojourn was designed with dual shield in mind, her Lazer charges off of shield hits, similar to how Sym can do that to help break shields. Except in ow2 there are no dual shields and what shields there are, are now weaker; which means its a fucking free fire zone. Normally you'd just have a tank go dive, but that's not possible, because you lose your front line and the fight is lost anyway, just now widow isn't what killed you.
Moira was also given a troll ability that she lost damage orb for and basically took a massive nerf across the board. But in the short term orb is worth the lulz because people don't know how to play around it.
Zen the robot asshole is a lot of fun until you encounter insta gib and he can't effectively pump damage all the time. Then you realize he is just an easy to kill dps which accidentally heals sometimes.
Junker Queen is not a tank and gets fucking shit housed by actual tanks to the point where it's comical. Sometimes it's fun doing JQ on JQ matches because their natural healing, battle shout, and general low burst damage turns it into a funny never ending battle. If you want to beat JQ every fight, just play rein and don't let go of left click. There is nothing she can do, I've never seen such a disparity between 2 tanks. In fighting game terms, it's a true 10:0 fight.
