I haven't spent a dime on this game for about 3 years. The reason isn't the prices, which I agree are on the high side though.
The reason is the state of the game, no real content, server performance, client performance, anti-cheat performance, management and treatment of community, bad communication etc.
I know some of this has changed under LO, but still not enough for me to spend any money on the game. So the ARMAS price level isn't the main motivator for my purchasing behaviour.
