I dunno, I think many people overestimate the cost of a sub... Going to the cinema cost about the same amount as a average monthly game subscription... although watching the movie in the cinema will be like 2 hours where during a month you will probably find more then 2 hours to spend in the game...
I understand that it can feel like wasted money if you only play 5 hours in that month but it's quite misplaced Unless you feel even more so when going to the cinema
