Ap won't get shield items like because a large number of AP champs already have built in shields.
That makes no sense, APs have actually an shield item
, and there are quite some ad champs with shields aswell
:
.
Also, by that logic ad shouldn't have ifesteal items because many ads have lifesteal in their kit or other selfheal....
Ad won't ever get a zhonyas because it would render ADCs unkillable
No, the reason why ADs didn't get zhonya's in the past was because they couldn't really use it. They were all about dps, so locking your self in a stasis for 2.5sec doesn't have alot benefits other than buying time for your team to help you.
However, with ad-casters beeing a real thing since a couple of seasons, a as-zhonya's actually would makes sense for champs like wukong to buy time for their CDs in a teamfight.
Ap won't get a cleanse item because AP has zhonyas
What has one to do with the other? Stasis and cleanse are two totally different effects with entierly different purposes....
Ad won't get a rabadons because it would be to snowbally and would just be a horrible idea.
The list goes on and on.
This is one off the big balance issues in lol. Ad already have multiplicative scalings with ADxASxCRIT(xCrit-dmg), AP has no such thing, so ap has rabadons for the lategame scaleing.
However, there are ad-casters which don't go for crit or AS, so they lack multiplicative scaleings, resulting in them haveing lowish base damage and huge ratios, which makes them very snowbally and usuallly strong midgame and weak lategame unless their kits are very powerfull.
Adding an AD-abbadons that has the same unique passive as IE and maybe even reduces critchance would help ad-casters to be less binary in their damage progression without adding another multiplicative layer on ADCs.
Ad and AP champions had rather different kits back in S1, but by now there are many champs with similar kits between AD and AP, especially when it comes to assasins and fighters.
