Trade Karma For Gems
I support this. It wouldn’t necessarily be game breaking because you have to earn your Karma just like you would gold. If you use your Karma for Gems, then that’s less Karma for you to buy other things as well, so it’s a fair and opportunistic way of getting gems.
If the conversion was set up right. This could help the economy. ( like if 5s = 1 gem then 50 Karma = 1 gem (rough guesses I do not know wt the gold to gem ratio is atm)). They, just need to maybe find a way to keep people from converting Karma → gem → gold. Which could exploit and would be tricky to set up.
