I agree with m00nbl00d.
I like standalone packages better.
Just think of the file size… not all people have Cable / DSL / T1 
Or provide an off line installer for people who want separate packages. Not a thing I like but it would be an interesting intermediate solution though.
This matter has been brought before. Melih considered it for some time, and when CIS finally came out he decided in favour of the current solution. It’s a marketing decission and Melih has stated that it’s final, if my memory serves me right.
So… your opinions will always be welcome, but… as far as I know the decission is made in Comodo and isn’t open for re-consideration.
