Do people re-level exotic armor if they get a better version of the same one? I have before with the symbiote helm, but that was when I rarely used anything but my Hunter. I just got obsidian mind from an exotic helmet engram and it has better stats than the one I had before. The old one has maxed experience, but I haven't dropped the materials into it yet. I'm debating which one to shard. Just wondering what other people have done in similar situations.
