So the scenario was this

Top and mid feeding like hell. jungler D/C first 5 mintues then rejoins preventing remake. Bot lane is sona and twitch. I, like so many other supports, see the power in locket and redemption but seeing that we were only with their lane winning I knew we needed to maximize damage for the fed enemy team. I build Zeke Harbringer first item.

I then spent the rest of the game being chewed out for building this item instead of locket or redemption. We had one team fight in which twitch went glowie and obliterated their team. They still bitched me out about not buying the item fad of the season. A shield from locket was not going to make a difference against the fed Darius, no one would live long enough in the front line for redemption to kick in due to a fed Yi.

So I ask, where is the flaw in my purchase? Just because an item is strong doesn't make it the GOD item of all items of all time. It would have been a shit purchase in that game. Locket and Redemption are not all powerful items. Read the game and not the latest op omfg roflstomp guide you just read. Have your own brain and think it through.
