I think that full ap kaisa is the best poke mage in the game right now. it wont hut as much as zoe but has low mana cost and cool down if you hit and you will most likely be top dps every game eve if you lose. also kaisa w upgrades the fastest of all her skills with just pieces of a luden and a doran ring
TL, DR: Full Ap kaisa is Pre nerf ap nidalee with way more range, thicker hitbox, and better follow up with her ult.
But unlike Nidalee or Zoe, it has a longer cooldown and deals less damage (for the most part). The range is it only comparison to them but it moves pretty slow making it manageable to dodge.
im not saying shes op if full ap, just that his is strong reliable and safe build path that many people have not tried.
With a lich bane and rabadon, the damage gets pretty ridiculous. Hitting your W just to ult in with a procced lich bane AA is enough to make them crap themselves and then spam your AP scaling Q. The changes coming that swap 20% of her AP ratio from W to Q will make her poke a little less overwhelming but keep her all in feeling strong. I think that's enough to solve full AP Kai'sa mid. (Though her laning will be stronger hopefully). I always start with Dorans Ring even when going bot just for the Q spamming and extra pot for the laning phase.
