While the idea is actually great, because this way the orks will have the biggest numbers but the weakest units, the problem is that those ork boyz will be actual human players.

And the problem with those units being humans is because the idea only works if the Orks play with strength in numbers, but many players are obviously gonna try to go on their own instead of playing as a team. And that's because it's f2p, because it'll attract alot of people at first that have no idea what to expect and how to play, so their just gonna try to figure stuff on their own and end up trying to go by themselves against an experienced Space Marine or Eldar and die, alot. And after that happens thei gonna start to blame the game and complain it's P2W and that only people who pay for it have an advantage, which will drive the players to do two things: either they are just gonna quit, or they are gonna buy the game to get the full experience and play on equal terms, and what's gonna happen is that the large numbers of f2p orks, which is a huge advantage the faction depends upon, will not be large at all and the orks will lose that advantage possibly making them the weakest side.

This is just a prediction I'm making, it all depends on how the f2p players behave, and it also depends on the game's popularity, what I see may happen is that the f2p boyz are gonna be players that come and go with the times, different ones each time, and the older ones either quit, or buy. But then again, this all depends on the game's popularity, and if it makes sure it stays as a popular game and doesn't shrink to the point that it'll only have a small cult following after a year or two.

Also, it may actually happen the other way around aswell, maybe the amount of people that want to play for free instead of paying is too large to the point that the orks will be laughably one-sided, which is why from the beginning I always thought that each side should have their own f2p class, but the orks would lose their number advanatge.

I don't know, I may be wrong, it also depends on how the boyz are structured and what exactly are their disadvantages compared to other classes.

Maybe I'm wrong but I just wanted to show my concerns.

Spending 50 bucks does not actually make anyone a better player. It might increase the propability of spending enough time to watch some YouTube "how to EC" videos to know the basics.
Answer to this problem is good enough tutorial.

Orcs will have paying members too, It depends alot on the level of cartoon sillyness in the Graphics style chosen for the orks. Too much sillyness and not enough mean mofo and people wont like it. If they go with the comic relief style ... orks will be in trouble from the day one.

If the game shrinks to "cult following only" status in 2 years , then we can write it off as a failure and orks having pop issues will be a drop in the bucket of problem.

f2p ork boyz aren't weaker they are more specialized and good only in a certain situation they are a lot less versatile than other player because they can use only one class.
the game is not f2p is b2p the f2p is more a trial.

That's why i point out in the end that it really all depends on how the boyz are structured, i'm aware that paying for the game doesn't make you a better player but if you a paying for a class that is much stronger than an average ork boy then f2p players are gonna feel they are at a sever disadvantage.

I'm personally aware of that, but many people are gonna see it only as f2p but with a p2w model. (sorry for the big font I have no idea why this happened).

What must be avoided at all costs is that this great game that comes finished as the now defunct "Warhammer Online: Age of Reckoning."

I don't think "Da Boyz" option will fail. Just about every multi-game community will have their main faction, with an Ork option for those that want to try the game and don't want to buy it. So odds are, the paying members of the community will also have paid Orkz to play with them. Add to that, some players will never pay if they can get away with it. A revolving door of Boyz isn't a bad thing, it fits the culture. Ultimately though, the overall success of Da Boyz model will rely on the paying Orkz.

This is definitely gonna happen but it's not the game fault, people just don't wanna admit that may be someone better than them or they got outplayed and people will look for any excuse because they are never wrong, it must be the game.

I am not a farseer, but I can predict in the future, after the game's release, that there will be threads from players of other factions who complain and basically whine about having once been bested in melee by a f2p ork, and that they should get nerfed.

This is something of which I am very certain, based on what the devs have said about this subject.
(There was something along the lines of "an ork boy cleaving a devastator in half if he catches him by surprise", for example)

There's one thing that can keep the over flow of orks in check if neccessary: tyranids.

Spot on.

What decides how the F2P player sees his first experience as an Boy is how the game tells he/she it's going to be. If there is a fixed, closed environment tutorial where he versus a few NPCs or something, the game puts on display his strengths and weaknesses versus some of the paid alternatives then they will have an intrinsic understanding of how they should expect their play to be.

If there is a showcase of sorts on how the Orks use their numbers, how they need to stay with their Boyz to be effective and hits on all the selling points of how fun it can be to overrun a position with a group of mates and scream Waargh then they will be less inclined to wander off into No-Mans Land and get ribboned by Eldar, leaving a bitter taste in their mouth.
