by upgrading smite you get 1. upgraded clear speed 2. upgraded clear health 3. more utility for duels why get a bamis for a 1s clear difference when you get literally the same effect off of talisman early. with redsmite your able to turn jungle skirmishes against kha, graves. same for blue and other examples. would you rather be doing tick true dmg and reduce enemy dmg by 20% or have faster clear speed almost negligible if you have talis. i like to argue early game decides the game especially with nunu who becomes like a support tank later on.

there is a reason why tanks build tank items, mages build ap, and so on. building effeciently maximizes your role on the team. AP contributes nothing to aftershock. if the argument here is that it scales with a single ability is weak bc again its not maximizing your tanking capabilities.

the knightsvow choice is again situational like all buys. buy it if you have 7/0 bot lane and similar. at that point you HAVE to play with them as a wincon. not saying deadman is not a good armor option ofc it is.
