Can we talk Max vs Monsters?
More specifically can we talk about why some champions have it and why some don't? let me throw some examples of champions which ether massivly aid steals or are played as junglers (not all of them but just the ones off the top of my head)
Without caps

With Caps


Now lets look at what the Max damage vs Monsters do, its a way for Riot to gate jungle clear times or lane pushing. but do you notice that theres some major things weird here
First lets look at the capped Champions with % health damage, so that's everyone on that list minus Hec (Sorry ponyman) So these are capped on minions and monsters in their % damage, thats understandable for Vayne and Kog, their marksmen, Lee and Vi? I suppose its to give Tanks a chance to clear but....wait... Mao, Mundo and Zac are also capped and their tanks... Meanwhile lets look at the uncapped % damage, Voli, Nidalee and Kha'zix, 2 Assassins and an early game tank.
Now what about the ADCs? Well As I said it makes sense for Vayne and Kog, their mostly single target, Lucian with the mechanics of his ult make a bit of sense too but Kalista....Ok I'll be blunt this WAS gonna be a simple "Why isn't Kalistas E capped vs Monsters?" thread but then I noticed that the Max damage vs Monsters is...well it's a mess we have more tanks with capped damage vs monsters gates then the assassins do, infact there isn't one, (unless you include poppy), Riot talks about how tank junglers have a hard time well for some of them, this might be it I mean the only champions with uncapped damage vs Monsters on that list I feel is justified is Nunu, Cho, Sej and Voli, ether because they aren't good for anything else (Nunu) or because they're tanks who are already having a tough time, Meanwhile Mao, Mundo and especially Zac are gated as TANKS.
Riot I think you need to go back and really look at the Max vs Monster gates, it seems to me you've forgotten that gate (I mean C'mon you didn't gate Nids Takedown on monsters when she already has a waveclearing E? THIS is one of the main reasons she's a good jungler) or you apply them on the wrong things (Zac and Mundo guys! They have to kill themselves to use their damn abilities!) I mean people clamor for tanks to be usefull again, you want tanks to be part of Jungle diversity well theres an option to bring 3 back, get rid of their max damage vs monster gate, while your at it put the gates of Nidalees Q and Kalistas E, at least with Nunu and Cho you have a chance to outsmite the combo if they mistime, as for Kalista let her wail on it for 10 seconds and not even they can outsmite her (Lucian is fine because its DOT)
3% + 1% per 100AP W which may I add is uncapped
