Just a question- how do you counterplay diana
Especially when she gets 100 ap+ and can either one shot you or outduel you with her passive. What would you do in that situation? I know, buy mr blablabla, then what? She is only getting stronger, and you're just becoming more useless to your team since you're building resistant to mages. She'll still outduel you, and can easily force fights. You can spend your whole time dodging her q's so you don't get one shot, or you can try to farm and then get caught and gibbed instantly.
all have potential to just destroy her. AP approach, rush Abyssal or Athene's (depending on how mana hungry your champion is) and shut her down pre-6 before she can start deleting you. AD Approach, Obviously rush hexdrinker. But she is MEANT to duel, so i wouldnt suggest a whole lot of melee, the only reason i put irelia and khazix in my list was because khazix is basically able to delete everyone late game. Irelia is just strong over all, with true damage and a stun/slow and good sustain.
