@Bond of Stone
that´s the 5th (?) change now to this mastery - and it still won´t feel good.
mostly because there´s really a huge philosophical issue with this mastery:
as a tanksupport you want to stand between your opponents and your carry, so they shoot you and he´s free to deal dmg...so if he ever takes serious dmg you sort of already failed your job. This means the 300health or grasp of the undying will always feel better for tank-supports, as they want to stay alive themselves so they can protect their carries from harm in the first place. So Bond of Stone would be perfectly fine for a Nami staying behind her carrie and absorbing some dmg if anything gets through the frontline - but then again, windspeakers is just more helpfull here still.
All in all the only selling point for BoS would be to ricidulously overtune it right now.
so maybe just swap it out for sth. else?
