isn't interactive and fun gameplay
not because it's fun but because it's efficient
In a game
Why though? Why does it matter to people so much how efficiently they can play if they're not having fun? What are you going to do once you speed through the entire game and run out of content? You'll just realize you never had any fun and then have nothing left to do. It's a video game. Everyone has their reasons for play, sure. But in the end a video game is made to entertain.
DE isn't twirling their evil mustache over slowing you down. These changes aren't some attempt to make you grind for longer. They're just working their way through broken strategies because they can't know all of them. Ember got changed, Saryn got changed (though right now she's overtuned, lol), Mag's been changed how many times? Spin2Win is dumb. When someone has an atterax (or scoliac, or lecta sometimes) I still find myself thinking "welp, I guess I don't get to kill anything." When you whipspin your way to victory nobody in your squad gets to have fun just because you're ruining your own fun too. People complain about how boring playing the most optimized strategies are. Maybe stop trying to optimize so much, take a deep breath, and enjoy the damn game you're likely paying to play.
