After playing a few games I've noticed, mostly as Pharah, that height can affect whether you get frozen with Mei's ult.
How high do you need to be to avoid being caught in Mei's ult?
- Do I need to be above her drone that is putting out the freeze?
Does jumping affect how long it takes for you to freeze?
Does standing on a nearby object, like a table, barrel, crate, etc., affect the freeze rate?
