I'm going to stop what I'm doing to take a moment here to discuss the virtues of a F2P game versus a P2P game.
First, and most importantly, most F2P games do not have the developer as the publisher.
Why is this important? Because if you have a suggestion, criticism or need to make a bug report for a game, it may not always get to the developer. That means the communication from the consumer to the developer must go through this awkward song and dance before it is heard. And that's just the tip of the iceberg. Because the publisher's goal is to make money then they are going to attempt to have the developer work the game in a way that caters to the publisher producing income.
Therein lies the catch. Some games which have been imported from the East to be published and released in the West are not published by the same publisher as they were in the East. That means the publisher in the West does not have to finance the developer as much. This creates a conflict of interest between the publisher and the developer, where the publisher is trying to get as much money as possible out of the game to make a profit, whereas the developer is trying to make a good game. Those two do not often work in harmony, and you often end up with imbalanced item malls, translation issues, boring or unoriginal GUI and more.
Just to be a bit more comprehensive, I will offer you a look into some of the fallacies that a pub/dev seperation causes in an attempt to cut expenditures for the publisher:
High pings on low server load
Third party client hosting (not hosted by the publisher)
Poor customer support
General lack of knowledge from publisher GMs (ex: THEY
NEED YOUR D

IAG.TXT OR THEY CANT TROUBLESHOOT YOUR PROBLEM)
Quick to blame the consumer for their client trouble
Overall lack of new features upon expansions
New features are poorly balanced
Botting is often not looked after as seriously
Exploits are often not taken care of in a timely fashion, ruining the game for some
Bugs can sometimes not be taken care of
Graphical user interface can be poorly designed
Imbalanced cash shop
Overpriced cash shop
Inaccessible server/website for no apparent reason
There are lots of reasons as to why the above may exist in a F2P title. Often it is the publisher rushing the developer to act somehow due to the publishers numbers beginning to level out. Furthermore, it should be noted that not all F2P games experience these fallacies. It should be noted though that often the reason for these issues stems from a lack of harmony between the developer and the publisher.
Right. So what makes a P2P game better? For starters, they aren't typically a money grab. The idea with a P2P game is they have a steady income they can track by checking their subscriber count. Each subscriber is always a paying member. What that means for the company is they have a way to track their income and project expenditures accordingly.
You often have servers on top-of-the-line equipment so pings are low. Servers are well-placed and easily accessible for most players. Developers often host their full game client right on their website for download, with a myriad of download options. Communication between the developer and the consumer is more often sought after, because the developers want to make a game that pleases their players.
There are dozens of reasons as to why in my opinion and in fact how P2P games are better than F2P games. Just reverse most of the failures of a F2P game as I posted above and you get something that looks like the following:
Good pings at all times, only suffering under the highest loads
On-site client hosting and downloads
Excellent customer service and support
Developers have a good understanding of the workings of their client and can help you when you have a problem
Client trouble is examined through client logging and can be submitted to the developers for inspection
Expansions are often packed with content
New features have been often tried and tested before release
Botting is taken seriously as it severely impacts the economy of the game
Exploits are taken care of in a timely fashion, keeping all players happy
Bugs are looked into with the greatest of care
Graphical user interface is often unique or artistic
No cash shop, so all players have the same opportunities
P2P games make the real world news more often than F2P, resulting in better marketing
Special events often give away meaningful gifts to their players.
Doesn't reading that list make you want to play a P2P game? Once again, not all P2P games posses all these qualities.
At the end of the day the fact is that P2P games look to level the playing field because you pay a monthly subscription just like everybody else. It promotes balance and good gameplay.
Remember: Quantity does not always equal quality.
