You can definitely feel the Fucking Hot Healing Chick! changes, but it doesn't stop her being a solid pick. It just means that you have to maybe pre-empt the ult to prevent deaths rather than it being a way of resurrecting. Junkrat seems pretty solid, the nerf seems fair and tbh won't make massive changes to his utility.
We play way better when we pick a strat and keep it simple. Some of our dives are pretty awesome!
