Multi Gold League, I feel like the rewards for ranking up need 100% increase. 50 gems for a rank is way to low. In case you don't know in "Gold League" you need 20 wins, not 10 to rank and there is no winning streak bonus. So at the minimum that's 20 games, and at this rank games are not easy to come by never mind winning.

Thanks for the feedback @Zakura414 - just to let you know I've already passed your thoughts onto the PvZ team (but forgot to post that I had!)
Cheers,
