It's your problem if you can't apprehend the eidolon's displacements, and get away enough from it to not be stepped on. Can't you just think about how big they are and how only one of their steps takes several meters to cross ? And they're not as fast as you say. Look how much time they take for each step.
thx for the hotfix, and pls don't bother trying to realize some dumb and paradoxal wishes from the community, asking for more difficulty, wanting to buff everything that's not and don't need to, and asking for less farm in a farm game while everyone who's complaiying buy all the new items as soon as they're in game
