General gameplay tactics and its features.

tactics are awesome! in Bayu, you need blind and slow, and then throw all your creatures at one enemy=),

it's a pity when you build everything, and it becomes uninteresting to play.

I still don't understand in which of the Heroes games there is a Conflux?

I thought it was in SoD, but it's not there, and it's not in the regular Might and Magic either.
The question is, where is it?
