Okay whether you either agree with me or the others who are flooded with coins we can ALL agree on something..
The coin system the way it is right now does not benefit ANYONE. Either you are completely flooded with them and they are just a background number like blitz cred and completely useless, or if you like to use restarts on songs, they are a hindrance. The coins should be used COMPLETELY DIFFERENTLY.
Don't make coins for the power ups. Period. Instead try to make rewards or something for people to spend coins on. People who are flooded with coins will then have something to actually do with them, and people who are bankrupt will no longer have to rely on grinding songs without powerups or jump through pointless hoops just to go for their scores. Everyone I talked to agrees that coins should either not be in the game, or not used for powerups.
Making the coin system for rewards or for purchasing different cosmetic stuff or emblems or anything makes everyone better off. Or how about if we can use coins to purchase new instruments, clothes, and such for our Rock Band 3 characters? It should have never been used for powerups which is an essential game play feature. It's like locking the 5th note on the guitar tracks and in order to hold a combo and get a high score you have to pay for it. It's stupid.
Everyone here is either complaining that they have too many coins and have nothing to do with them, or we are complaining that the coin economy is ruining the gameplay flow. So why don't we just ditch the coins entirely for power up usage. They should have never been implanted for powerups in the 1st place. Using coins to punish and not reward is just bad game design.
Set up a coin store and reward players who have a ton of coins. Make coins REWARDING and not PUNISHING. Use coins to GIVE to players and not TAKE away from players. Only issue now is in order to implant something like this, you'd need a major patch and a lot of rewriting. I hope they can do something about improving the coin system so it's not used on powerups.
Or how about improve Rock Band World and add features to spend the coins on. I like that we can spend coins for peeking on our opponents in score wars, but you can add a ton more.
But at the same time, ditch them for powerups. It would be cool if we can have something similar to Platinum Artist and such from RB2 in RBB, but you have to use coins to pay for an icon like(50,000-500,000 coins for stuff like these). It's these little things that can improve the game a lot more. Or use coins for events and such using RBW. Coins have a lot of potential, but the way they are handled right now IMO is just bad design.
Powerups are not a reward, they are a SPECIFIC GAMEPLAY MECHANICS REQUIRED FOR THE GAME. You are not meant to play this game without powerups.
