Good to hear, schmee schmee. Any fine moments? Nice, gruesome details?
To answer the question of "how much plasma" in such a small point game... I've played 500 point games (keep in mind we're talking about 1K) where I've had 4 Plasmas. Death Guard. Lots of people play it, and Khorne dies against it unless they stay away from monstrous creatures. Every game I shoot the crap out of their HQs, and when their zerks arrive, plaguemarines eat them allive. It's a very consistant massacre. I occasionally lose 1 or 2 plaguemarines in the final assualt, but escaping unscathed is also common, and my army isn't even that shooting oriented. A shootier SM army will destroy WE before they even make it to assualt, and int he unlikely scenario that they do, AM HQs tend to be able to take care of them very easily. The only way that World Eaters have beaten these common tactics is by not using monstrous creatures. Modest HQs, fire support, a good core.. you know, that crazy thing called balance. It occasionally helps to win games against other balanced forces (of which there are many).
Monstrous creatures can be used in larger games. Wait, let me rephrase that: Greater Daemons can be used in larger games, if used with Chains.
