If anything I would say Ekko is one of the healthier examples in terms of the implementations of large shields on damage orientated champions.

Only real time it was seriously problematic was when its base values were large enough for it to be useful for Ekko when he was built tanky, especially considering the resistances he would be getting from his items. Yasuo's in turn is also easy to pop in lane, and really only amounts to shielding him from the occasional basic attack, or preventing him from being burst down with instantaneous damage.

As for Riven... well, she is actually pretty bs.
