Riot is already aware that he can not use tiles we are using, specificly the tree and bush. The castle tiles and all the ones you made are fine.. but terrains and such are not allowed to be used by Delteria.
It's not about competing, its about wanting to offer a sense of uniqueness to players on both servers. You have a much larger staff, and I am told that you are in the process of redoing the tiles that you can't use so thats good. So I hope that screenshot with you and the trees etc is with temporary usage of my graphics.
