User blog comment:ClariS/AD has Diminishing Returns!!/@comment-83.208.159.162-20120828093605/@comment-4881935-20120828175353

I just want to clear this out. Here's an example to explain my point.

Pretend you Mundo and there are a lot of healing reduction effects that weaken you. If all the healing reduction were nerfed, let's say it now only reduce to 75% instead of 50%, then this would feel like a buff to Mundo, even though Mundo directly was not buff. The truth remains that this was a healing reduction nerf that Mundo just benefits.

This is my case with Synergy and Diminishing returns. Overall, they make the same lasting impact, but they are achieve through different means.
