Exotics yes My favorites are actually a couple vanilla legendaries I've had since shortly after I started (day 1) - a relatively run-of-the-mill sniper (Epitaph) that rolled in void with a couple good perks (field scout now trashed) but it was that scope I was looking through the first time I saw Atheon crumple - wouldn't break the game to be able to infuse it or other legendaries
