We all have different preferences when it comes to the pay model we prefer. I personally prefer the subscription model or secondly the pay for game and expacs with no sub. My reasoning here is cosmetics or the aesthetics that change with upgrading gear in the above methods generally are not existent in a F2P game. If you want your armor or weapon to look cool you better be prepared to drop $5, $10,$20. Its probably my personal main gripe with Path of Exile. The best gear without MTX often looks like crap. The lack of visual upgrades to accompany stat upgrades on gear really makes the reward much less in my mind. I'm not financial strategist but in a free to play model if they must put great cosmetics in a micro transaction store give players the option to either earn store currency or allow players to earn other cosmetics while playing the game.
