can you like not make tanks really terrible at dealing and taking damage on the howling abyss? what the hell is their purpose then?
chose one if you must and not both.
meanwhile broken things like 
get to deal 112% damage on that map.
who was in charge of these changes?
Not as lovely as Akali's 18% dmg dealt and -18% dmg taken. Build mr and she still 1shots you with 1 Q and R. Ryze for some reason also has damage buff in ARAM, among other bullshit champions. They fucked up this mode with their "balance" changes.
Because tanks are op af in aram especially vs AP teams which are the most popular in aram , but I agree the balance is a little shit there , I'm fine with the tanks nerfs , but why Kai'sa and Akali are buffed? if anything Kai'sa needs a nerf in aram.
Most tanks are nerfed because they're fucking OP in ARAM, because Warmog's is still busted as shit there, and, for obvious reasons, tanks are one of its key users.
Most tanks are also incredibly oppressive in ARAM even ignoring Warmog's. The classic example, and almost certainly the champion you're talking about, would be Maokai.
Kai'sa gets bonus damage because she's really not that strong there. She either has to stall until almost full build with an actual build, or she has to go pure AP and then fall off after 1 item. She's also pretty reliant on having her comp be able to protect her.
