I will NEVER EVER BUY GOLD MARKS. EVER. until this is fixed. There is no reason to not have a confirmation when spend rl currency like this aside from either being too lazy to code it or just wanting to grift what ever extra cash they can.
I think it's mainly "just wanting to grift what ever extra cash they can" but it also has some "being too lazy" powder in it.
They say setting a confirmation button for GM use is a "bad idea from marketing perspective". However, we already came with different ideas on how to solve that issue, for example, a "Don't show this again" for those whales that want to spend 5.000.000 GM on a round. Even other ideas have been brought to the table, there's just no interest in solving players problems.
That's why it's mainly "just wanting to grift what ever extra cash they can".
Don't bother, they DON'T WANT to listen.
Plain and simple.
PS: The new design has set it's priorities, you can barely understand what's happening, but hey, if you want to use gold, the button is a quarter of your screen so they make sure you won't miss it.
