Why did the rewards structure suddenly become unfair just because (one or many) players can now solo the raid? If the structure was fair before why not after? Players have been "screwed out of (top-10) rewards" ( @Mugz722' words) for years. Why is that suddenly a problem now that players can solo the raid?
In guilds where many players solo the raid every time (raid after raid) the rewards get distributed more evenly since in case of ties the order is random. Why is that unfair? And how exactly would "evening out" the rewards be any different (other than allowing players to score zero/low and still receive OK rewards)?
Yes, more total rewards would be nice for your guild. Agreed. But what's the reasoning behind your request?
