Especially the bosses further along the way. Upgrading them still renders most of them useless to the upper tier of players as their lowest value of employed warriors and weapons in many cases already exceeds the legendary values of the drops. There is no incentive for these players to chase these bosses other than for token xps.
Seriously KANO, we have 5 world bosses on rotation, shouldn't this be more like a limited item stat's when get to legendary, considering it takes forever to acquire these drops? 5 bosses can make a elite, 10 then can make another elite=can craft 1 legendary on rotation of 5 world bosses takes forever to get these.............. <<<via Sandlot the movie
