I have a Rapid Fire ability in my arsenal, where it is written in black and white: "You can move at full speed and are immune to all disabling effects while channeling this attack." In fact, this is not the case, and I have checked it more than once. Initially, I discovered this when I was closing Volcanic Rifts on Galen, my character fired one shot and was stunned by a meteorite explosion, then my character was thrown back by a Lava Golem with one of its attacks during the action of the ultimate. I thought that maybe this just does not apply to this, or the developers forgot to add everything related to Volcanic Rifts to the list, but no - Guardian of Galen also controlled my character with one of her whirlwinds. One of the minotaur bosses in the Black Forest did the same, and a player did the same with some incomprehensible vampire ability. Why write that there is immunity to any control effects, if in fact there is none at all?
