Are the achievements really such a good idea?

It just doesn't seem like it.  The medic was weak and needed some upgrades, but what about the other classes?  They're already good enough at fighting.  Look what happened with the pyro's weapons.  Instead of a gun with some sort of disadvantage, we get a new ability added to the flamethrower, and a superpowered version of the old flamethrower.  The axe is weaker?  Well no one used the axe when they had a flamethrower or shotgun, so is it really a disadvantage to be weaker when someone isn't on fire?  And because of all this, until every class has their weapons, there will be some sort of unbalance.  But when they all have their weapons, will they even be balanced?  How do we know they won't pull the same thing they did with the pyro, where rather than the new weapon having a disadvantage, they just give the old one a new ability and come out with a more powerful version of the old one as the new weapon?  And will the weapons all even be balanced?  Is about doubling the number of weapons, a bunch of them having some sort of advantage, really a good idea?

i'm pretty sure valve playtested each patch to ensure that it was balanced.
all the weapons are alternatives. there is not direct this weapon is superior

a lot of the people say the vampire syringe thing is far superior.
theres two ways to survive
run and suck health while you keep running
or kill them faster than they kill you.

the uber guns i see a good mix in games

the ubersaw. seriously now. 25% ubercharge? well assuming your already charged a bit or already hit someone three times.. i doubt its gonna help too much. is it worth the 20% speed drawback or you can kill them quicker without dying. adono i like the regular saw too

i think the guns are pretty balanced them self.

the old flamethrower greatly needed this boost. they're an offensive class but completely useless in the beginning of the match until they could push ubered people away.

valve is doing a good job with balance. just a lot of people qqing. its like wow. MY CLASS SUCKS CUZ I CANT WIN. "IM A MAGE AND I CANT KILL WARLOCKS" exactly why warlocks are the antimage. -.-"      

The point of these updates is to provide the player with more choices and create more diverse gameplay, which it is doing.

It may be doing that, but it is making the game frustrating near update times. I mean, the influx of pyros is just plain annoying now.

Yeah, but think about all the players who, becasue of the free weekend, will now buy the game and ensure the longevity of TF2. Long after the free weekend.

And how can you really hate on new content anyways? It's like hitting the dog with the newspaper he just brought you.

Just because something is called an 'addition' doesn't mean it isn't just a 'detraction'. That said, I don't think the achievements and rewards are an inherently bad thing, I just think they all should be implemented at the same time.
