Righteous Glory on Melee Carries

So I've recently decided to start building Righteous Glory as a 2nd item on Tryndamere. I understand that the stats are largely wasted, but that movespeed active is absolutely amazing. People cannot run from you without flashing, and even then you will still catch up to them and be able to get the slow from Righteous Glory. I understand that the item doesn't technically give any combat stats other than health. However, its ability to allow you as the melee carry to stay on top of at least one opponent and be able to get off those sweet, sweet autos is just too strong to pass up.

What about champs like Yi, GP, and Jax who can actually take advantage of the catalyst portion for sustain? Any opinions?
