Grasp of the undying...
Who thought this was a good addition to the game? It's the tank version of Warlords bloodlust it's just pure toxic in my eyes, being able to steal 3% of your max health every 4 seconds means that you... basically don't ever lose laning phase trades against someone who's using any other one of the defensive keystones. Just look at Strenght of the ages, 300 health on a mastery is alot, however it takes 30 cannon minions to get it fully stacked, which is going to take a long time, making it pretty much useless early game. You almost won't notice the effects of bond of stone in a solo lane either, 4% damage reduction nice, but the real power comes from being near your allies, so it won't help too much in lane. Grasp of the undying gives good sustain early game and extra damage and being able to do that every 4 seconds is ridiculous, and it just becomes stronger the more health you stack. What I'm saying is that tanks already have enough damage, they already have dead man's plate, titanic hydra, steraks gage, black cleaver and frozen mallet (yes that item still exists). Either the scaling would have to be reduced or they'd have to increase the amount of seconds in combat required for it to activate or something along those lines.
