Unfortunately free to play games do tend to make such stupid design decisions which are usually driven by the need to generate more revenue through the cash shops

This is what makes the HUGE divide between subscription and free to play game quality.

Subscription based MMO's spend all their time concentrating on how to improve the game and how to keep the players subscribed. The Free to Play mmo spend all their time in an attempt to keep people playing but overshadowed by the need to drive more people to the cash shop

Inevitably free to play games just piss people off by forcing them to spend WELL OVER the normal subscription fees to get ahead in the game, or they simply make bizarre design decisions which are driven for financial gain and not because the game requires that change

Thats what I have encountered anyway
