F2P ,What did you think? ... I just uploaded my progress just to show you that I can be without improving anyone (which I am 4 months old and I have not yet improved anyone to 3-4-5☆)
I can maintain my range for a long time even if I don't have much power I only have 1M.
I've been playing for over 2 years and everyone seems to be ahead of me F2P wise. At the very least, I have a stable amount of rupees now, I'm just suffering elsewhere. :(
