Tanks only have 2 defensive stats, DPS classes have 4

Gonna be doing some maths here on the damage

Tanks only have HP and resistances(armor and MR) while damage dealers got AD and AP, Armor and magic pen, crit and AS but not all classes use all of them(obviously). Think about it, with so many offensive stats to deal with tanks it's no wonder the damage meta has happened. Armor is useless when you stack armor pen + / and the same goes for magic resist when a mages has full mPen.

Ok so let's say you take 400 damage that's either physical or magic from an assassin, ADC and mage without adding effects.

If you get jumped by an assassin with and they deal 400 damage even if they that isn't true we'll 400 as an example, they will deal 319 to a target with 90 armor and 222 damage with 200 armor. combined that is 49.4 total armor pen on top of 39 flat armor pen. against a squishy target, that might be a bit extreme but for tanks it's a nightmare. 252

Full build ADC's with the same damage is 438 (non-crit: 173) for tanks and 563 (non-crit: 252) for non-tanks then they crit with

For Mages that do the same damage with it's full damage for anyone with no MR and 266 for anyone that has

As you can see, armor might mitigate more damage but ADC's have crit and AS to bypass that issue while mages can deal true damage to anyone that doesn't have have over 55 MR. In other words, Resistance don't do jack shit but riot still continue to increase damage done in the game. So unless resistances and HP is increased for all classes accordingly.....

Expect to die in less than 0.01 seconds when you get jumped.
