Even thought it's one of the best schemes in the MMO world. Not for publishers, though, hard to believe, eh? Such games won't discriminate you in anything and usually update often (like this one). This particular one even allow you to level in all possible classes with little to none restrictions. Here is a list:

1. There is a limit on how many professions can have maxed out disassemble skill, but you can max-out another skill by taking points from one of the maxed-out skills and it's only for disassemble - you can craft everything with no limits as long as you level your craft class.
2. You can't distribute bonus points for Summoner and Scholar separately (INT and MND respectively) since they both are Jobs of the same Class. That easy to circumvent with bonus points reset, though. Which is really cheap and you won't need to use it often anyway (unless you decide to play only these two classes and never use any other class... I doubt so).
3. You limited to have up to 8 characters on each server, but you can have all classes and jobs on one single character, so you don't really need all these twinks anyway... unless you want to made and army of waifu and it's your own problem.
4. You can't alter all aspects of your character appearance with Aesthetican and limited to only a few, but how many games allow this for free anyway? How many allow this at all? You will also get one potion for full appearance, race and gender reset after subscribing for 2 months, so even if you fk up at start you will be able to fix it later for free (but only once, all extra resets are paid service).

Do you know even one F2P MMO which doesn't discriminate you in the end? I know a lot of F2P games which is easy to play for free up to the top level... but when it comes to make a top gear... if you have no money you are fkd and doomed. All of them.
