Why not above Legendary? Don't you think they deserve merits? Kidding. There's no more rank above Legendary but I have no problem now if theymos adds one lol. However, there are some club like 10k merit club, 5k merit club and I really hope that you will help all that guys too and consider their post history review offer 
I'm not actually looking for merit here. I'm not requesting a review either but it would be great if you would accept such request too because it would help to distribute the merit perfectly. For example, most of the times, I'm out of smerits (only last few days, I have few) and I wasn’t able to merit some of the local post which I thougt deserve merit. I know I can report them to LoyceV's thread in reputation but I only report post there which is somewhat a great contribution only. If a post deserve 1 or 2 merits, I don’t feel reporting them on that thread.
Just my 2 cent but I appreciate your effort. Not everyone spends such huge time behind  reviewing the post.
