I didn't even read the rest of your post. This is all I needed to read to immediately know that the rest of the post would be filled with bad estimates, and things that many people have said would be truly harmful to the server. That, or things that many of the more experienced/veteran players have agreed on that are horrible ideas.
70%, huh? That pretty much accounts for all the people that play this game with less than 1000 hours. So, I guess you could say that "estimate" is almost accurate. But, not really. I wouldn't really consider any of them to be "graalians". They hardly know anything about the game. They don't know how Era works. They prolly couldn't even walk around Era without needing their maps. Basically, even if any of them actually agree to a "dropping EC" idea, they don't know the game well enough to be an effective judge.
There are much easier, more efficient, less hurtful, and smarter ideas to solving the issue with unfair EC distribution. This idea would lead people to scam EC, and people would be getting 50 ECs a month from scamming.
