What do you think the best way to build her is? Is piercing shot more effective than multi-attack? Or does she simply cost too much in the current cheap-effective meta? (Which is the reason I stopped playing years ago, amusingly enough.) Does someone else perform the ranged damage(Frost) output better?
I would use piercing shot as it is not a basic attack effective against split units and cloak of skulls and so forth. She does need help with champs that can chill. I agree they should remove secure fonts and make her a little bit cheaper. I always thought she should have chill 5 anyways as part of her core.
To get the most out of K'aeyun, run a Chronomancer next to her and watch her triple hit regularly, especially if you run her with Savage Exploit.
I run her with furry hat and pilgrimage. Multi 1 and perserverance for upgrades. The hat+pilgrimage combo makes her damagr ramp up to insane levels, especially in frost amp.
I really like this combo. I like it even more on K'ento. Get her in a good spot, and you can even drop Soul Frost and rake in the nora.
