I think 200 per is the only way this is feasible. To players having a hard time getting enough, Etheric Light is probably more valuable than vanguard/crucible gear. 200 per Etheric Light also makes it so players aren't pulled away from HoW content. I agree that 200 marks is expensive, but I think that is the only way the idea works in both the short term and long term. But thanks for disagreeing and not being an asshole about it.
