can you add a converting system

The actual exchange rate is a tricky one but it has to be fair for those who play a lot and for those who maybe don't play as much too.
The situation with Rainbow stars is and will be a game breaker for many.
Even the prize map is becoming a serious issue for many players. Quite simply it is very difficult for many people to get the satisfaction and fun out of playing the game and earning rewards with this ridiculous currency system.

We earn coins which atm are absolutely useless once the Rewardotron is empty, which for many of us was empty many months ago.... unless you use the xp machine, personally Id rather just play the game and only have used the machine a few times since Founders to help out characters I'm not keen on playing.
OR cant finish the map for the Wizard and you can spend some on him. Sadly not for the legendary upgrades you missed from the map though as they will cost you rainbow stars.
And if you want buy bulbs to finish the map they will cost you 250 rainbow stars for 5 bulbs (cant remember the other prices for more bulbs) anyway that's a huge amount of rainbow stars just for 5 bulbs.

All this has to be taken into consideration... something has to be done about it as it has to be one of the most ridiculous, useless and unrewarding systems ever created.
As @ToastedSarnie points out once the map is complete there is little to no motivation for playing any more that month. You can just play watch your bulbs be earned but not applied (after you have saved your 50) and amass crazy amounts of coins that at it stands atm you can never use... there is no reward for playing more that month, in fact as time goes on and coins etc amass... while watching earned bulbs float away nowhere.... it feels more like a punishment.... and pretty boring.

....and thats not counting tacos, marshmallow and sheriff badges... we can change them for coins.... oh wait........ 😃

Edit: If they limited the exchange to 15/20 stars a weeks they may as well not bother.... that would also be ridiculous  as costumes cost from 550 to a 1000 rainbow stars and legendary hats seem to be costing 750... so really 15/20 stars a week isn't going to help the situation at all I'm afraid.

Edit 2: What would be nice in relation to the "lost" bulbs situation would be if we could donate them to someone else who was struggling to have the time to complete the prize maps... this would many of us very happy and be a nice thing for the community overall 🙂❤️
