You could say the same for most Melee ADCs.
I mean honestly read their kits:
Resourceless, free 35% crit chance, free AD + even more AD the lower his HP is, 4 second AOE slow that reduces AD, a giant dash that does heavy AOE damage and also gets CDR on crits, and to top it off, the absolute inability to die for 5 seconds while he crits your face off, which just so happens to be the only ability in the game that can be casted while hard CC'd.
A targeted gapcloser that hits 3 targets AND makes him untargetable AND can crit AND has it's cooldown reduced by basic attacks. A sizeable heal that also gives him massive damage reduction. An ability that passively gives him free bonus %AD AND can be activated to give him AD scaling true damage on every basic attack AND no mana cost. And finally, a relatively low cooldown ult that boosts the hell out of his movement and attack speed for 10 seconds AND makes him immune to move/attack speed slows for the entire duration AND passively gives him global CD resets on kill/assist just for having a point in his R.
I don't have time to list the amount of bullshit in this kit.
Give any traditional ADC a kit that looks remotely like these and they would be broken beyond comprehension. Yet these guys are still considered a liability at best in competitive play for the sole fact that they lack a singular attribute common to traditional ADC's : Range.
The only identifiable advantage these guys have over regular ADC's are that they are easily able to protect themselves from most threats, an advantage that is completely nullified in competitive play since people will be working together as a team anyway. Other than that, they can't siege towers unless they splitpush (another tactic that is unviable in organized play), are at heavy risk of getting instagibbed before they get close enough to get out their DPS, and even if they do manage to get close enough, they are very likely to get cc'd and/or kited and focused. Therefore, they are REQUIRED to have unfair bullshit overloaded kits in order to remain even a troll pick in comparison to a regular ADC. Fact of the matter is that in a MOBA, having range and therefore the ability to be flexible with your positioning always has and always will be an extreme and unfair advantage that has little counterplay by nature of you needing to jump into the middle of the enemy team in order to deal with it. (Similar problem with
)
It's the same issue with
. You are putting a champ infamous for getting kited, in a lane against a ranged champion and another champion who's sole function is to help the ranged champion kite you. This situation is completely unfair for Mordekaiser, it's not Morde's fault or the designer's fault that his kit is toxic and full of invisible power and bullshit mechanics, fact of the matter is that as it stands right now, he NEEDS to have multiple unfair advantages if he is going to be anywhere near a usable pick against a ranged botlane. If he is going to be an ADC replacement in this meta, Mordekaiser CANNOT be healthy, not because of his kit, but because of the fact that he is laning against people that should be making his life hell. Either he has the tools to work around that weakness (which are typically minimal-counterplay due to the nature of range) and he pisses off everyone with his ludicrous damage and free tankiness, or he doesn't have any way of reliably dealing with ranged enemies and as a result gets his teeth kicked in every matchup and can't do anything about it.
I commend Riot for trying something different by shaking things up and insisting on making a bruiser botlane viable, but for it to be healthy they need to follow up with a large-scale rework of the ADC class as a whole (in the vein of juggernauts) to give each marksman more identifiable strengths and weaknesses, instead of "We all do the same thing and right-click you to death just with different powercurves and you will lose the game if you dont have one of us on your team". As much as I despise Kalista's current iteration, I like how she was designed to bring something unique to the ADC table with extended support interaction and a unique way of dealing damage that favors objective control over massive crits, just not the other tacked-on shit she has in her kit. Same with the Tristana rework, which makes her less of "right click you to death" and as a tradeoff gives her best-in-class turret siege. Speaking of which, they also need to make it possible for melees to siege turrets because as it stands it's impossible to do if you are missing ranged AD, and maybe that way Mordekaiser won't be required to have the ability to 2-shot you under your turret with a massive shield that absorbs all the damage while a ghost dragon takes most of the aggro etc. etc. noninteractive mechanics Mord needs to be remotely competent at the ADC's traditional job.
