The thing people are not mentioning here, is that eventually we'll probably get Rainbow Crystals added which can be used to obtain strong units from the trading post, and can only be earned by discharging gold+ rarity units, with the amount gained based on the rarity (event units however get almost none). For that reason, it's likely best to hold on to duplicate plats you don't plan to actually use.
