Tbh, I've always thought shard farming was "shady" since it first started. If you kill trash it should stay dead in that instance, at least for a few days like other raids. The fact you could reform raid after 15 minutes and endlessly farm the trash for shards, even without the use of "creative positioning" has always been a bit fishy, at least to me. So I applaud this fix, now Funcom, start working on other broken crap in your game!
