There really is no best or worst, each can be good depending on the situation. Wound works amazing on a Miko/Tank combo. While slow works amazing on Caldarius, or he could easily get away most of the time. Silence is perfect on ISIC or Ghalt when they are in their ultimate. As for a good team CC set up one is for the choke points next to the first sentry on Overgrowth. Stun an enemy as Kelvin, use Shayne or Ghalt to pull them into your area. Use Kelvin’s wall to block their path back to the sentry. Or as Montana knock them back into a wall then have a Boldur do it to once they try running.
I’m having to guess the best combo for CC is 5 Orendi’s using Nullify with push effect when standing around an enemy in a circle. I feel as though that combo might break somebody. And probably cause the world to end.
Every CC is worth using if you are in the right situation, wound on an enemy team without a healer is useless. While a silence on an enemy that favors their basic attack over their abilities, like thorn or Montana, can be almost useless unless you can time it just right to negate their ultimate.
And as for my favorite CC, that would be slow, it helps when chasing an enemy, or running from one. Stun tends not to last as long as a slow.
My least favorite would be Stun, I feel as though it is a cheap trick in a fast paced game like battleborn, it’s too easy to stun, and for most characters, one stun and you will probably die if the enemy gangs up on you.
There really is no overrated CC, just underrated, I feel as though not enough people focus on using slow. Most people would go with Miko’s Stun instead of the spores dropping along the way as the bomb flies. Have a nice line of slow and it works great on clusters of enemies, especially minions.
