Honestly I like what they did with the shadestep, walls, and rifts etc. They are on the quickest cool down timer. But when I'm playing a game of countdown and I won't have my grenade up for maybe another 2 rounds it makes me think should I even throw it? Especially suppressor nades. I hold onto the for the last 4 rounds to shut down supers in hopes that I won't get creamed by a roaming smash or pole dancer.
