Yorick's pets don't take damage as intended

[I have to keep posting this since two people are stalking my account and downvoting the thread beause they don't understand that this is either a gameplay bug, as the link below proves it is not intended any more. Or just a text bug, since they do have this effect and it doesn't say anywhere in the abilities that they have that effect.] Prior to the rework, ghouls had the added bonus of -50% damage from AoE effects.

After the rework, no mention of such a passive exists anywhere in the spotlight, League's site, or the game's information. In fact, the only official reference to how Yorick's new pets take damage can be found in a response by Meddler on this thread: https://boards.na.leagueoflegends.com/en/c/gameplay-balance/nE3bmJUI-are-yorick-ghouls-supposed-to-die-from-1-auto-attack-late-game

In it, he says explicitly that mist walkers are intended to die in one auto attack, but the defense they have against AoE is their health scaling. Late game, with a tanky build on Yorick they'll have around 600+ HP, so most AoE effects won't be able to kill them in one attack. Early game, however, it's safe to say that they're intended to die to AoE due to the lack of health since they have 0 armor and 0 magic resist.

However, somehow the 50% damage reduction from AoE attacks was added into the code for both mist walkers and the maiden without any indication of it being intentional.

I tested this with Poppy's Q, because at first I thought it may be a bug with them not taking some part of that ability's damage (either the %HP, flat, or scaled damage) and I found that it was simply 50% of the total-- and yes I did check the math on the other possibilities.

This is a strength that is completely unintended, and makes Yorick a stronger counter against several top laners early game than he should be while also beating their scaling to late, as this also effects the damage they take from Sunfire Cape.

[EDIT] For clarity, no other pets have this effect. It is completely false to claim that all pets take half damage from AoE. Shaco's boxes and clone take full damage from all sources. Malzahar's Voidlings do in fact have MR and armor to mitigate damage. Zyra's plants have about 8 different damage mitigation conditions. Heimerdinger's turrets have armor and MR as well and also take increased damage from melee basic attacks. Tibbers and Daisy also take full damage.

This bug is unique to Yorick, and effects both the mist walkers AND the maiden.
