Why? What's the real point in getting Armor Points? Is it really that valuable to you? Just be active on the site and you'll be fine with AP. Don't even pay attention to it, be active in the forums, playing games & leaving game comments and it'll rise by a lot soon enough.
I don't like this idea. Also, AP is going to be changed in AG3.
I don't think it is a great idea. Not many people care to AP so much and some people use it on the weekdays and don't use on the weekends and it would be kind of unfair. A good way to earn points without spamming is being active as Matrix said. And in AG3 points won't be like this now, it won't matter if you earn points but it will matter how you participate in this site.
