does any champion use conditioning?

I like to pick it on junglers, since waiting 10 minutes for the effect is usually not a problem. Unless I'm a squishy up against burst champions, I feel like I get more value out of conditioning.

Conditionally Sejuani, maybe Mundo?

I like to grab it on Ornn.

I take it on any champion I off-tank with. ( Lux, Zoe, Kayn. ) It's an amazing pick up for any champion if you KNOW you need to be tanky. I've seen Merc Thread, Banshee's Ahri run it when they see a heavy AP enemy team.

likely very few, it doesn't give a lot while requiring you to wait 10mins to get the benefit which is a long time in this meta. Bone plating and arguably second wind is better early on and not to mention that armour stacking hasn't been viable for a while.

Ok

real question is who uses shield bash

garen, mundo, maokai, malphite, poppy, ornn, i mean alot of good tanks,
