#Aftershock Entitlement
Why do so many believe that they should be allowed to get resistances for free and invalidate an entire class of champions, assassins?
Some of the most oppressive mid laners were already oppressive before this rune. If you want to get really fucking tanky then you should have to sacrifice a part of your build to do it, ex. buying fucking tank items, or relegate that responsibility to your tank.
Aftershock is a crutch to give certain champions much easier early game dominance when the worst abusers have absurdly high damage, AoE CC in their kits or burst. Most of them have range as well.
Aftershock should be removed, period.
But on a serious note, your post is kinda stupid. You think bruisers should have to buy LDR/Mortal Reminder or just shouldn't be able to duel tanks AT ALL. "Just let your ADC do it." IS THAT ACTUALLY YOUR ARGUMENT? Then you'll complain that ADCs are too dominant, and also split pushing will be dead because bruisers can't kill tanks your short-sighted scenario.
Also, the champions who use Conqueror don't have absurdly high damage or burst, or even insane mobility (these aren't assassins, who have an engage and escape). Nor where these champions "oppressive" before this rune. In fact, ~90% of them SUCKED before Conqueror. Are you memory blind by bias or do you just refuse to look at data?
Also, taking away a class's keystone without offering an alternative is just asking them the class to be useless. You also provided ZERO statistical evidence in your argument.
