What i think should happen is that there should be a bar at the bottom of the rank page with your amount of ap for the month what do you think?
Why do you want the idea to happen?
I really don't think it's that useful unless people are absolutely dying to be the Current Leaders board. Though, it would be kind of cool to see how much AP you've earned in a month, but then again, it's useless to know that unless you're going to be on that list.
I'd prefer if it calculated your average AP, but then again, both of those ideas do not need to be implemented, if your dying to know, simply record it yourself.
I don't think this is a must-have feature, because you could simply do the math yourself. ~Take the AP from the end of last month and subtract it from the AP at the end of this month.
So, there really isn't a huge demand for a feature like that. But I like that your thinking for ways to improve AG.
I like the idea I have to say but really if people knew how much AP they needed to be on the Current Leaders there would probably be alot of spam but id that didn't happen its a good idea.
