Riot there is a reason everybody uses Thunderlord's now
And it's because you nerfed literally the entire ferocity tree keystones, and then buff the cunning tree masteries at the same time, which then made Thunderlord's much more superior. You can't just gut the ferocity keystones and expect people to use them.
Oh, and I had a tank with Thunderlord's too, maybe you shouldn't nerf veteran's scars to make it viable on squishies (who rarely use it may I add) so that tanks won't use it.
Just my thoughts though.
