5% Zerg completion exp rewards with leaderboards if you can match or top fastest score.
5% Obliteration exp rewards for killing every creature, hitting every optional, smashing every crate.
To honor the two very different but fun playstyles in DDO

Epic Desinity Karma Pool not tied to a specefic sphere.

A "Recorder charmer" reward drop clickie that a character plays to coax a rare spawn out of hiding. It would need to be a rare chest drop (a sorta 'meta' Inception-esque type idea)

A Champion slider from 0% to 100%. First person in sets the scale. Running Korthos elite with 100% champions could breath new life into that old chestnut when reincarnating. Suddenly protecting that crystal not so easy. Solve the forums wars.

Daily Dice is doubled in epic levels.
