lbh,
I'm not talking about balance in real world terms, or even gameplay terms - i'm talking about balance in terms of certain races getting yet more ships (which they didn't necessarily need), plus getting Armageddon-level ships, whilst a lot of the other races get left behind.
I'm a Dilgar player, first and foremost. I love the fluff, I love the ships, and I love the rules and how they play as a fleet. I also reckon that there is room for improvement with the Dilgar, and seeing all of the other races getting improvements and newer ships, makes me wonder what sort of future the Dilgar have within the game. The same can be said for the Drakh - the new kids on the block, so to speak, and they too get left out of Armageddon.
I haven't read the Armageddon book yet, but from what I've read on the forums, it seems that if you're a Dilgar or Drakh player (Raiders players - are you also misrepresented?), the book is pretty much useless. Whether this is deliberate or not, I don't know - perhaps there will be a V2 of Armageddon, just for the Dilgar and Drakh. I won't hold my breath, though - it seem the main message of the book is "if u can't beat 'em, join 'em", so I'll be expected to buy one of the fleets that got upgraded with a precious Armageddon-level ship, just so I can compete with the bigger boys. It may be a null and void point, but if the likes of the Drakh and the Dilgar players don't get the newer toys like all the other bigger kids, interest in those races may dwindle.
I'm not a 40K player anymore - the stuff got too expensive, and someone already mentioned the flaws with the GW business model, but at least ALL of the races got something new every once in a while - it would be nice if the Dilgar and Drakh got the same respect as the other races.
