I wish that Xur would sell exotic shards again. It's kinda annoying that to infuse into anything exotic you need to use a shard. Especially now that it hard to get them. Even the "three of coins" requires a shard to buy them and those aren't reliable in that they will give you anything. I don't see why they took that away from Xur, granted he has become kinda useless the ever since year 2 launched. This would make him a little bit more useful, well at least in my opinion.
