Devourer seems to be the problem.
Correct me if I'm wrong, but a very high % of champions that would be getting this item (if not all) will be auto attack oriented AD champions, right? So why is this item magic damage. It's just beyond me, it makes everyone into Jax, where you have to build dual resistances in order to try to counter them as a tank. Don't even get me started on how ridiculous this is on Yi, with devourer he deals physical, magical, AND true damage. There is no countering him. He will tear you apart.
"Just get Frozen Heart!" If only this actually made a large enough impact. Sure it'll slow his attack speed a bit, but this requires me to invest solely in armor, not health or MR, which lets him continue to tear me apart with his magic and true damage til I can build mr and health. I just don't understand why this exists, someone please enlighten me.
Edit: Why has this become a Warwick discussion, I was simply asking for clarification and opinions as to why it was magic damage. I don't care for the whole Warwick mess going on right now, I just think this item feels VERY powerful on auto attacked based champs who deal mostly physical damage. But then again, being a tank isn't in a very good spot lately anyways, so I guess that could be part of the reason why.
