I guess that the real quest is to get 15k more than your previous best... i think that those scores BELOW 1 million are pretty much valid, but not over that...
drakuni, i'm keeping my boosts on 600% and i'm making profit ;) It really depends on are you active or idling a lot, if you idle, i'd say that keep it in something like 250-300... not sure, cause i'm always active :D
I agree with Sinafey, there should be more of "th" achievements like atm 180th :) It would be also nice when you buy hp,mp and attack in battle arena that the amount would raise depending on your lvl (or something) ... But this game is better and better everyday :P
