Now Now guys/girls play nice, To be honest I have been thinking over the last few days to add an 1m parse leader board and a 500k one to this but I was gonna check with everyone's consensus first I was going to post this earlier but had a migraine yesterday so didn't get around to it and with it, however it will be up to the community to decide which one leader board they will support more remember each of these values favor different classes and spec's with 1.5m being sustained 1m being a balance and 500k being burst.
edit: of course i would have to amend the rules to fit with the new structure but that wouldn't be an issue.
Sounds like too much work. 1.5 million is fine, you'll just get less people parsing because it is already a pain. Just do what you're doing, it's all good.
