Why Madred's/Kitae Bloodrazors are disabled in TT? People stack health, the developers know that bruisers are the dominant class, and it'd prevent people from stacking tons of armor and not sacrificing too much durability. If there's a reason (which I'm sure there is, the developers are smarter than me), I don't know what it is.
Also, there isn't really a replacement for it. Blade of the Ruined King isn't as effective, since it deals damage based off of their current health.
So yeah. If someone could enlighten me, I'd greatly appreciate it.
