Every time I see an Akali, Vladimir, Katarina, Garen and so on buying a Doran's ring or any mana items like a mana crystal, I just think... why? It's not even recommended for a reason. None of those champions benefit from it at all. Similar with mana items (Unless being built into Trinity) but still... why?
This often happens in Bronze but even silver/gold when people are trolling or rage quiting like another variant on 6 Mobi's. Of course, I know some people might buy it out of habit if they don't know energy and mana aren't the same but still... it's so infuriating. What's next? Mana Yasuo and Mana Riven?
