Turning it in isn't the issue, I just don't think you should be forced to trade it in to remain sane considering how large an investment it is. Maybe things have changed now that 100s rain from the sky on a daily basis in Dynamis, but I never knew of - or even heard of - anyone trading in their Relic currency midway through completion, and that's not because going to Castle Zvahl is difficult. I don't see why Mythics should be any different.

If I could carry 30,000 Alexandrite in the space of 5 inventory spaces, I could chose to sell it all and get two Relic weapons depending how things work out come Lv.99, trading it in completely removes that option. As it is I either have to buy half a dozen mules to store it all, or one mule and waste far more money than I'm willing to on fame and inventory quests. Regardless of what option I'd pick, sending all that Alexandrite back would probably end up being the most annoying part of my life so far - and I'd hate for SE to dethrone Rebecca Black.
