The problem with this Meta

Tanks do to much damage and 100-0 skishies despite being tanks. Assassins do too much damage, build full tanks and still 100-0 skishies. Adc's suck, lifesteal suck (you don't survive long enough to use it), crit sucks (doesn't keep up with reliable spell damage everyone else has). The only good adc are the ones that are the that have stupidly overtuned abilities. Mages are still mages. Turret suck because everyone does too much damage to them while they do little damage, esp inner towers.

Fiora is broken because of her percent true damage and everyone building tank. Giving her percent health true damage was just not a good idea, she doesn't need damage that will be dealt no matter what when with the reliability she has from her mobility and W and she can proc her passive way to fast. If you keep it you will have to rebalance Fiora everytime you make the slightest defensive/AD change. Percent health or true damage, pick one rather then nerfing her worthless E.

are OP because everyone wants tankyness to survive burst and damage, preferably burst damage to burst whoever doesn't have defensive items yet.

Everyone does too much damage aside from those who don't and are underpowered.
