All the news looks to be good news, especially for those who have been sitting at level 50 for a rather long while
My main concerns from the posted information would be about star coins, namely:
While star coins are disabled, will the shop category still be available? (basically, can we still get 100 extra gems a week?)
Will players retain their star coins until they reach level 75 when, presumably, they can spend them again?
Just really hoping there will be no 'Star coins will be converted to gc automatically' quick fix...
