EO attempts to balance binds and ailments by having something called accumulative resistance.
I think at least in untold games it means that the first time you hit an ailment the target gains 50% resistance to said ailment.
So let's say enemy has 25% resistance(0% means immune/100% means no resistance) towards sleep, you inflict them with sleep and their resistance is now below 0 which means they become completely immune to sleep. However this resistance fades over time, so after about 8 turns or so you can attempt to CC the target again. And this works both for you and the enemies so neither side can get perma locked into a CC chain.
