Yes, why not?
I'm not spending half on thiis game than I used to spend on "free" to play games. I don't have extra retainers, we only get an expansion every two years, and the vast majority of cash shop updates are items we could get ingame at events, so I barely use the cash shop. The last exclusive we got was from... three/four months ago? I don't see how this game is as demanding money-wise as you mean.
I also don't see them using the same outfits again and again; don't we get several brand new outfits with every update?
