My first set of boxes gave me some pretty cool crystals that I'd never have bought on the GTN (white is way too expensive there) and Revan's Reborn mask, so pretty happy, latter boxes included XP boosts (BoP of course) on level 65 characters. So yeah, the rewards of the event shouldn't be things that you litterally cannot use in any way shape or form. I'm fine with weapons on the wrong characters, at least I can unlock those with collections, but the XP boosts I find almost offensive.
