This is likely to spark some debate, but I think epics rank high on the list of "Worst ideas in EverQuest." People felt a sense of entitlement to the damn things. It wasn't uncommon for people to cause guild strife getting the fool thing, only to quit their "fun" guild and join the uber guild that smartly required people to already have the items so they didn't go through all that malarky. Not that I'm bitter about it. mind you.
It was the Cleric "click stick" epic that broke many guilds and player's spirits. EverQuest had a hefty experience point loss on death. The Cleric epic was a mana-less, instant-cast stick that gave you 100% of the xp back. [Edit: I stand corrected, it is indeed 96%. That's what I get for trusting my memory. What's 4% amongst friends?] If memory serves me right, it was also the only class epic that ended up being a have-to-get.
