Yes, it's absolutely fucking depressing.
Lucio's fucked. He's slow, he loses the speed you do manage to build up way too fast, and superboost being gone has murdered a lot of movement potential.
Vertical control is indeed gutted. I mean, there's no other way to put it - I simply feel like I've got much less movement control when moving up and down a section of the map.
Mercy is fucking up the game. Blizzard just doesn't understand that Resurrect is too strong of an ability to remain in the game in its' current state.
With every patch I have had exponentially less faith in Overwatch team's balancing - at this point it feels like they made it fun on accident, and now that they're "refining" it - it's getting way more stiff and less fun. It feels like a flat MOBA to be honest, where mechanical skill matters way less than hero combinations and game knowledge. You have to be a fucking nerd about it, basically. You can't just get into the game and be good at a character and pull it out by the skin of your teeth anymore. It's all hard metagame from here on out.
