Seriously, if you don't buy your respective "must buy" item, you just feel underpowered. It feels like so much power has been shoved into a select few items as if they are "Keystone Items" and the rest are situational modifications or "Lesser Rune Items". Heck, Bruisers could be argued to have TWO must buy items in Trinity Force and Black Cleaver.
While it is inevitable that some items will be more common and more powerful than others, have you tried playing an On-hit Champion without Guinsoo's? Or a DoT Mage without Liandrie's? Or an AD Assassin without Duskblade? You just feel like a shadow of what you could be.
as a damage item it would massively favor one AD class over all the rest.
on any low cooldown mage.
