Yeah I looked at your prices when I was suggesting what to do. The reason I suggested dropping the luxury boxes prices is because if you look at my arena you will see that it isn't easy to sell 10 luxury boxes at expensive prices.
The reason I suggested dropping CS to 100 instead of 110 is because 110 will sell some more seats but you are also building 40 more, and so if you want to make full use of those 40 you should drop the price further.
Same reasoning applies to the LT, if you put it to 45 you might sell an extra 100 seats, but if you put it to 40 you will probably sell out all the seats which means you can expand and earn even more.
Definitely try and promote this season, div 3 is a lot more fun and challenging. I'm hoping to promote this season as well :D
