new ferocity keystone idea

Warlords needs to be changed into something more focused on % damage than into Life Steal, it might help you in 1vs1 but it is super niche.

But yes, this mastery was done before, that doesn't mean it wasnt good, I'd prefer this mastery on certain champions over Thunderlord or Deathfire any time.

About Niche masteries: It would be better if Warlord caused you to deal % damage depending on how low you are in life and added a flat amount of life steal (reduced to half against minions).

And, Deathfire is not Niche, it just feels not worthy, yet it has more damage capacity than Thunderlord. I have been abusing it with and , yet it needs Magic Pen to work well, I'm now planning to buy Illaoi to see how things go with her and DFT, since I believe her tentacles, spirit test and ult proc it. BTW it does Wonders with Corki and some Magic Pen items, the AD ratios on it have allowed me to get some sweet kills (when they run away low in life and then DFT kills them).

The one that really is super Niche is Stormraider, yet I believe the only thing it needs is to proc at 25% and not at 30%.

Warlords is strong on a lot of AD/AS champions, and it works with EVERY ad champion. DFT works with every mage well, it out damages thunderlords mid to late game on most mages. This keystone is so massively underwhelming compared to its competitors you'd be better off taking anything else.
