It's not about making them "plane touched, vampiric, and advanced-" at least for me.
For me it's about supporting the unexpected. Throwing a troll at pcs the first time? Fun... OMG it's not dying!!! Throwing them at the PCs the 3rd time? Get the fire swords out...
Making monsters quick to generate for me lets me throw together monsters that keep on scaring the players because they never know what to expect. THAT to me is the fun of D&D.
I have to admit that I can understand your desire, but I think that what you want is mostly supported already, regardless of monster generation system. There are 4857 different monsters in the 4E Compendium which means that with approximately 35 main monster levels (plus a handful higher) and about 4 levels of monsters are worth throwing at the PCs at any given level, there are about 555 different monsters that I can throw at PCs in any given encounter.
I'm sorry, but for non-special monsters, I don't need to generate a single troll that fire doesn't work as well against. I have 555 different monsters I can throw at PCs at each level of which 530 they will never see (and the number is typically 700 to 1000 for levels 1 to 15, and dropping off to 400 to 500 at higher levels because not as much material is available for high Paragon and Epic). I don't need to quickly generate a special troll and if I do, I just take a pencil, cross out what I don't like, and add in what I do.
For special monsters, I agree with you. But for me, a special monster is a re-occurring villain. One that will show up over and over again. If I'm taking out the time to generate a special monster, I don't want it dead in 30 minutes. And yes, I want it to be somewhat quick, easy, and painless to create. But, this is relative. It can take a bit of time because it's something that I want to fine tune anyway. I want to take my time and design it, I don't just want to slap it together.
But for non-special monsters, I really don't care. As long as I can grab some powers in the vein of what I want, have a template for level for attacks, defenses, and hit points, I'm good. The monster doesn't have to be really well designed because it's going to be dead 15 to 30 minutes after I introduce it.
But, I typically do not create monsters. As long as I have a good search tool to search for a monster similar to what I want, it's all good. In 3E, a lot of monsters are not online, so I would have more of a desire to create my own. It really takes too long to search through monster manuals for monsters.
This is why PC rules and monsters rules should be similar for attacks, defenses, hit points (although monsters can have more), ability scores, etc., but their generation rules can be totally different due to their utility and duration in the game system. Monster creation has to be fast and easy because monsters die so quickly. But, the fastest monster creation is just grabbing something someone else already created.
