User blog comment:ClariS/Why Xerath's Passive is Bad/@comment-5001455-20130317110020/@comment-4881935-20130317163557

I actually would disagree with that Nhan. Now, ignoring the actual strength level of passive (meaning, ignoring the actual number), the core idea behind most passive will either ehnance a champion's strength, promote a certain style, improve a certain aspect, create counter-play, or create a new dynamic.

For example, like Eve's old passive (take 50% less damage to minions). Granted, this passive is weak, the idea behind it is that this should allow Eve to gank champions in lanes a tad bit easier.

And if you believe this, do you mind showing me a champion with a passive that doesn't do anything I have said.
