Ok so here is the rundown of what I'm trying o do here. Tanky DPS and tanks are hard to counter mid to late game because of their bulkiness and resistance to damage. There is an arsenal of damage items made to counter these types of champions but hese items are too efective at doing damage to squishies and in the end not as effective at destroying tanky champs as they are squishies.
The biggest problem is that teams can stack defensive items on these tanky dps and still out dps damage stacking champs. Now I can agree a glass cannon should die fast to focus fire but there is no reason for a glass cannon to be out dps'd by a tanky dps. Basically because of the damage resist of tanky champs they deal more damage than the glass dps champs do because they are taking considerably less damage and still doing average damage and it is normally oupled with CC.
My basic idea here is to make pen items less effective when used with AOE damage and mage anti tank items gain strength when the rest of your champions damage is losing strength. Madres here for instance will do less damage to a squishy and more damage to an armored tank and at the samge time if the tank is stacking armor then you will be doing much less physical damage when your madreds is doing more damage so it balances its self out. here would have to be a damage cap on neutrals so it couldn't be used to kill baron and other creeps really fast.
I also think there needs to be more itemization items for hybrid builds.
Let me know what you think.
Last I have some ideas for updating current items and or adding new ones.
