Why is grievous wounds on''mandatory'' items

Every mage buys

Every ADC buys which they can then upgrade into and adc's aren't the only ones building this item

It's nice to have a counter to lifesteal, but this is seriously hurting any sustain reliant champions, those who have this as part of their kit or are supposed to build some to compliment their kit or build like a lot of tanks and juggernauts and some fighters and the obvious champs like swain and vlad and also mundo

It just seems wrong to me that something as powerful as grievous wounds is put on such must buy items, not to mention it lasts for days if you ahve any sort of dot like brand for example you can apply morellos grievous wounds for like 14 seconds Or apply for 5 seconds per basic attack, which is completely dodgeable ofc, if you play shen, who has no sustain. . .

Just makes no sense that nothing is given up for cutting certain champs kit power in half in fact its just there even when there aren't any healing champs which speaks volumes
