Actually amazed at how bad MR itemization is...
I find it amazing how everyone complains how ADC's are mostly irrelevant in the current meta, how mages are much better due to having decent damage over time, burst, utility, CC and good itemization (not questioning that) and that ADCs must be buffed to not become irrelevant.
The only buff the game (and every character) needs are more and better Magic Resist items, not even more damage when damage is already out of control.
When mages don't even really have to buy penetration until late game and even when they do, that penetration ignores total MR anyway, you know something's wrong with the game.

or a Void Staff

is bad because it pops with literally anything (seriously, Luden's Echo
can pop it, how stupid is that) and is extremely unreliable.
Hell, I've started using Edge of Night
due to how much more reliable it is, despite the lower stats.
still, the shield is almost guaranteed to proc and might just save their life. Or if their character has decent AP scalling in some abilities, they buy Zhonia's
ffs.
Magic Resist items are only good in characters with high HP, so in every other character they are subpar unless they have something else attached to them (AS in Wit's End
; MR reduction in Abyssal Sceptre
)
For dual resistances:
(
not often bought, but still gives decent MR and the active can fuck most mages)
If you want some AD with it:
