Stuck on obstacles and swarmed/CCed

I've died more to dodge rolling into a small obstacle, getting stuck, then CCed, then swarmed in maps over one shotted from a boss. Dodge roll still doesn't allow you to escape being surrounded by a mob. Additionally, I get stuck on random stuff moving through some of the maps.

And NO, I'm not getting stuck or heavy CCed from sprinting. I find that feature more irritating than useful.
