I have to say how incredibly excited I got when I saw this<3 No, I didn't mind the payment version at all, and found the flamers obnoxious; sorry to hear about the personal/internal reasons, as I was fully on-board with a secondary means of funding which actually gave members something too as opposed to just donating.
HOWEVER~<3
:3 NOT ONLY does this make things "more fair", by making things difficult but perfectly obtainable over time, rewarding active and long-time members most while keeping it out of newbie hands but giving them a goal and reason to stay active; it ALSO gives those long-time members something to work for!

I was actually thinking just about a week ago, "What does someone do if they get seven Lv110s, even just seven Ancients, really, and don't want to release? I guess they just stop playing, maybe donate resources to friends or something.." Not anymore~<3

I've been a lot more active than usual recently, but all I've been doing is trying to keep my dear Dark Dragon among the top, so I can at least be ONE OF the "first" to see the new stages. :3 Otherwise, most my dragons are in underleveled gear and just kind of sitting around. NOW, I have MOTIVATION to get even more active, gear them out (so they'll produce more resources so I can buy more coins), etc~<3 :3 So while it's still going to get to a certain point where instead of seven you have, say, eleven Lv110s and nothing really to do, it's gonna take a LOT longer. :3
In short, while I did like coins for money despite not being able to buy, and sort of wish both options were still available in fact, I believe if it had to be just one method, this one shall prove far more beneficial to DragonAdopters and its community overall~<3 Epic work guys.
