Makes sense indeed. I have added at the end of the article the reason why i didn't take cooldowns completely into account. Over a short period of time, only very spammable ones needed a special mention for this analysis. With per-second outcomes like you use, Sona's heal clearly becomes way more significant, making her low ratio more efficient yeah. Simply if a Jax just jumped on your ally, Taric's/Soraka's instant healing amount is more likely to save his life, that's the kind of situations i focused on in this article.

Might just make an article with your formulas for more complete data, if you don't plan on doing that yourself?
