Yeah you're probably right... There's more that could be done to recharge.
ALTHOUGH...what if Dispel actually dispelled ALL of Olivia's Mimic abilities? You heard it here first! Dunno if that would give Nomos himself a big boost, but it would certainly give Dispel a hell of a boost.
That would certainly help! Though I do still think mimic has to be re-worked and properly defined. Endless guaranteed ability stacking + no limit as to which new abilities can be gathered makes for mimic to be a problem so long as it operates that way.
