So what do you guys think about grievious wounds?

So,what do you think about about "Grievious wounds"?

I for one am not a fan of this mechanic,but from a balance perspective it's good to gave a mechanic to deal with healer or champs that are strong with self healing abilities.

On the other hand,I find the items a bit "weird". GW should be niche effects that u buy when're facing enemies with high healing power,but Morellos is a core item on most midlane mages,while EC is much cheaper and upgrades into a AR pen item that with it's other stats could be an item on it's own. Why aren't GW on niche items,but items that you can literally buy in any game and still do well?

Why are they on damage class items instead of utility and tank items? Supportd are the ones that should primarily buff/debuff allies,while tanks mostly are magical tanky creatures that might lack damage but back it up with high durability and utility?

Why doesn't seem like they're so easy to apply? EC just required an AA and burst mages utilize Morellols really well,since they're burst either kills you or leaves with low HP and little survival.Why not let it stack or something?

Am I just looking at it in a wrong way or might I be on to something? P.S. Sry for errors.Wrote this on my phone
