As is concluding that ADCs have any greater chance of hitting a backline target in a teamfight than a mage, many of which have higher range (
are just the most extreme of examples). As it is, burst damage tends to be less consistent and reliable than DPS, as it is much harder to counter. This is why you have had the "outplayed by Syndra" meme for forever, but when do you hear that about ADCs outside of this board and it's "sustained burst" memes?
So if you want to talk realistic, lemme tell ya what. You will rarely see any ADC winning a fight by hitting a backline target (not hitting one when the teamfight is already basically won), or reaching one safely to hit to begin with. Why do you think
is currently god tier? It's almost like killing tanks isn't even hard for him, but for most other ADCs you're stuck with max 300 dmg crits against a tank. ADCs don't always get to stand still and right click forever (although the meta does favor supportive team comps, which I can't say is an ADC problem), just as mages don't always get access to the enemy priority targets. I'm not saying mages WILL reliably burst enemy squishies, I'm literally just defining burst for you. And DPS focused ADCs don't burst. I'm sure you can make a case for individual champions like Corki, but the items don't burst by themselves.
And I've realized that I've made the mistake of playing your game (or just boards in general) by judging balance based on end game scenarios that rarely ever happen, but when they do, heavily favor ADCs. But to see that the most hyper-scaling class in the game doesn't reach the burst numbers of many mages says a lot. Are there bullshit interactions with crit items like on Vayne, who can 3 shot with 2 items? Yeah, but since you all cried for no changes at all when Vayne buffs were on PBE instead of offering constructive criticism that would make for healthier changes as compared to her current state, you'll have to wait a while before the 3 shot Vayne build is no longer a thing. And when I suggest changes that make the scaling of ADCs less volatile (aka energize item nerfs), what I get in response is "No, I don't want them building PD either!" Like, what do you want then?
I will say this, before you misjudge my intentions. I come here to discuss balance, not to try and get people on a nerf or buff train or to convince Riot. So let me say it: I don't think mages are OP, in fact I could care less if they were buffed. I like having to adapt to changes as a player, it's refreshing.
But when I say ADCs don't out-burst mages, I think of moments like this.
