On the WWE Universe Facebook page with over 1k members I have screenshots of it with basically how much gold it costs without having to use the 15% boost. But if you just play non stop from start of streak to end it takes roughly 1 hour to get to 100 and about 2k gold in refreshing.
As you can see there is vip, think he just doesn't know about it. But I got it after spending way too much on the game and it doesn't seem to change how fast they respond. I tried explaining how to stop the glitchers but they were confused on my very carefully worded message.
