I used only 2 times including now, may I know what is the advantage of using it except more pets, more quest, auto price shop? Thanks in advance.

The benefits are listed here: here

oh thanks for the help XD

Also, you get more quest (including battle quest) and no ads. Also, once you fill up those ten pet slots the GA doesn't give you any more extra.

I totally understand now, thanks alot for so detailed infor, much appreciate XDD

No problem. :) Have fun with your GA.
