@ Meddler. Can we get some clarification on why Warlords is changing again?

It was stated that Warlord's Blood Lust was in a good place and that the healing might need smoothed out. However I can not help but feel that by changing it to scale off total AD that it just pigeon holes the Keystone into being a Carry Only pick. Why change it so soon after it's release? Late game healing is already ludicrous on any carry, who's ranged or has high mobility, and builds a Blood Thirster or BotRK and I am sure it's not Warlords that makes or breaks that.

I understand it's former iteration was somewhat oppressive early game but the current version has a lot of versatility on other classes like juggernauts and fighters who don't build tons of AD or potentially crit. It was nice to have an option in the ferocity tree that didn't require so many caveats to use.

I am also wondering if this is being done to encourage less lethality ADC/Assassin builds by giving them a reason to build Crit? Still I feel like this makes the keystone relevant to only a small group of champions while leaving others less viable or attractive options.

Thanks for reading!
