But...but...but...tank meta. :P
Seriously though, I'm still of the opinion that not everyone should have the ability to deal 8% true damage on hit. I can play freaking AD NAMI with conqueror at this point and the tanks would still have to respect that I deal dumb amounts of true damage.
"lel gl winning with conqueror Nami kid"
But winning isn't my argument - of course I'm going to get blasted to kingdom come by literally anything that isn't a tank. The point is, even with something that ludicrously bad, I can keep a tank from doing his job just because I took a single rune and built a bunch of armor penetration. Right now, we're in a meta where literally everyone has far more aggressive options to take against tanks than tanks have against them. The least we can do is acknowledge that there should be something tanks can do to handle the people who take all these options on divers. Divers are not supposed to feel so empowered that they can dive a tank under his tower with full confidence they're gonna cap his ass and live.
I don't think the solution is bashing the items - items that stand against tanks are supposed to exist and have a purpose - more than I think the solution is giving tanks a break from true damage everything. Conqueror is honestly the most limiting keystone in terms of design space ever, because if anyone can be a tank slayer, what purpose is there in playing tanks?
I guess my official answer to "gl winning with conqueror Nami" would have to be "gl having a tank meta with conqueror, admit this rune fucks over an entire class of champs."
