I do get gold but I don't feel getting 100k when dealing 100k xD I can take a close look tomorow. Would be more 10% at best. Also did you take in account that your hp (aka troop) were also increasing?

And for the rewards at world boss, it depends the day. Sometimes the difference btw top 10 and 50 is neat and so player try hard more. But when it's 1 gold medal against 2 silvers I really don't care ^^
That being said, I will try to check gold earnt, it could be better than actual gold map when you reach an amount of damage.

Talking about crap thing, I checked the port and I'm amazed at how many super scam trade you have. Only weapons and "event" things are good. Seriously, 20 standard ration + 10 fast tickets for a simple troop change that can be bought for 30k gold ... I fail to understand, and you have worse ><
