Maybe it's because I've been playing something else since Tuesday.
But I don't really care about lethality on its own killing tanks. I'm honestly confident that in the tank update, the base stats of tanks are going to get such a nice buff (while the resistances provided in items are nerfed) that lethality items will be pointless against them and better intended for low resistance targets (AKA: all squishies).
Why am I confident instead of worried?
"Give me the serenity to accept the things I cannot change, courage to change the things I can, and the wisdom to know the difference."
And I'm kinda tired of worrying about things to come. I have enough to worry about.
