I did not see many cons from this site but maybe they could improve their payment methods and add more of those rare payments so that they can attract a lot of players into the site. This should work well to help the site earn more visitors and who knows, this may even help them gain more revenue as well. Another flaw that they could work on is the speed. The site is so slow when using it in the phone version. That makes it hard for players like me who are always on the go. This should be a priority for them since this is a key factor for many players who want to enjoy games with just a touch of their phones.
