His W is countered by so much it's not even funny.
 * Disruption skills in the form of stuns, fear, knock-ups and knock-backs (77 champions can utilize 94 skills that directly disrupt against 34 who can't).
 * Healing reduction skills that Miss Fortune, Fizz, Varus Katarina and Tristana innately posses. (3 of these don't have an interupt so that leaves 80 champions to 31 who can't counter Yi's heal.)
 * Healing reduction Items that anyone can easily buy, namely Morellonomicon and Executioners Calling.

So basically your team needs to consist of 5 out of the 31 champions that have no innate counter against his heal and then refuse to build items that counter his heal directly. Otherwise, not OP.
