Actually against a hybrid team, Adaptive is a good point to invest.

It's also help against situation where their both AP and AD is strong but only 1 get fed, so you can concentrate on building 1 type of resistance instead of having to build a cloth amor or mantle

But my full 0/30/0 will get both of that point so i dont bother it anyway.
