Do not nerf Demolish rune.
I know someone people dislike the demolish rune
Quite honestly, of the many runes introduced, this is one of the best. Why? Because originally, we have seen only 2 types of roles excel at punishing roams or sieges. ADC and champions melee split pushers like Jax, Fiora, Yi.etc
If you die in lane against a Fiora post 7 minutes with a enemy minion wave, you can say goodbye to your turret. The same applies if you decide to roam from your turret with one of the champions mentioned above. it also applies late-game in split pushing scenarios.
Do you know when this never happens? With tanks. You can roam, you just don't get punished for it. Even roaming vs a mid lane AP champion is more punishing because they gave AP champions the ability to do more damage to structures based on their AP. Now, if you roam against a Annie, you turret will will take nice chucks.
Tanks needed that. They needed some ways to be effective outside of being glorified supports. Yes, that's what tanks were last season. With the exclusion of Cho and maybe Sej (mostly due to her passive), tanks were mostly running around CC'ing champion and using
