They could make it so, that if you have done the 2.5 epic, then the reward from "an epic retelling" will have an additional "extra shiny" looking option. For example: with 2.0 completed, the wizard ornament has a blue gem in its mouth. https://everquest.allakhazam.com/db/item.html?item=125916 With 2.5 completed, it gives you an optional version that spews blue flames instead. Giving an ornament a clickie effect might result in a conflict, if the weapon already has a clickie-effect beforehand...
most wizard main handers don't have clicky effects tho? you know i'm actually sold on giving it twincast clicky! would be awesome.
