I think this is a great idea for example if doing a "same rarity" conversion it should show all eligible sets given the lvl of the IO being converted ditto for "same category"; obviously wouldn't be needed for same set conversions
I skipped the taunt & the one ST power that needs momentum to be used, Defensive sweep can provide a crazy amount of Melee def to a resist based build allowing to focus on Ranged & Aoe IO bonuses
