gaspop: I used to play HOMM 1-3 all the time when they were new but never played the campaigns. I thought the standalone maps were more fun (and easier). But now that I've been finished MM6 & 7, I've decided to finally play through the campaign of HOMM 2 and 3 for the story.

HOMM 2 seems easy enough so far, but it's struck me how big a part luck plays and the reliance of crap AI. On mission 2 for example, when you start out in the middle, there was really nothing I could do on my first attempt as two of my opponents went for my castle almost immediatley. On my second attempt, two of the AI's bugged out and just kept walking around in a loop, never advancing. The third stuck to his starting area for a bit longer. Giving me the chance to build up an army strong enough to defeat him once he finally attacked.

What are some good strategies for HOMM2 and what class offers the easiest campaign? I've always gone with Knight for example, but perhaps that's going for the most difficult route.
