All characters are above level 40 (except 5D's they are at level 35). I have completed all missions in DM, GX, and 5D's. I have completed all puzzles. I have 5000 gems and I do request Konami to add new way to gain gems in game other than in-app purchase or convert 10 coins into 1 gem or even 100!
the creators of the game should be increasing the gem counts from 1000 to 10000 or more. we've been purchasing gems for cards but it's still not enough. we should be getting more gems so we have more time to get more new stuff.
u literally just said you need 4 hours to get 1 gem, if u duel LD that would be impossible, unless you are soooooooo unlucky that dueling 4 hrs won't get you a single gem, if you duel 4 hrs i bet you can get more than 100 gems, some duels may give you 5 to 10 gems, so dueling 4 hrs should get you a decent amount,yet you say it like the game is greedy and all,u sure it's not your problem?
