What think should be done is that, well I'll say it in this way. I only play RTW and so I would like just to be awarded with RTW avaters, and you can do in this way. say you've have 10 in your postcount then it'll say "congraulations! Because you've reached 10 in your post count you may choose one group of avater from the selection we have. So let's say this guy wants a RTW avater, he would choose a RTW group of avaters. Simple!
