well, adding multiplayer does not need to directly affect the gameplay/balance/ units - only gives option to play with a friend.

On the other hand when my girlfriend played Homm 3,4,5 at the beginning of her play experience she was angry that pc can play better (she was attacked by overhelming armies of enemy heroes, would she play with experienced human, she would be humiliated like really, luckily she played with me hot-seat and I let her win every second time)
But the point is that exactly the anger of being humiliated by AI heroes, motivated her to improve her tactics and after few weeks she completed even the most difficult maps and even on impossible difficulty (some of them even I had to cheat to complete them)...

So multiplayer may be scare, but that gives the add-on fun to the game, really.

Another example - I played Homm 5 BETA testing multiplayer, I played the demo map only for 4th time, but I realized that one elven hero is overpowered (speeds up all units), I played with one of the proffesional testers (I think he was even developer) who believed that he got all the smart moves and that undead are the most overpowered, so he tried to smash me with huge army of zounds of skeletons very soon at the game (bought a ship and wanted to defeat me in first month) and my joy when I defeated him becaouse my archers had 3 more moves agains his undead army was greater then winning any single player scenario.

On the other hand true is that from beta till 3.1 patch homm 5 was changed due BALANCE many many times, what took many good things from the game.

For KB TL I read many "tactics" that are (should be) THE SOLUTION for winning impossible and it is hard to believe for me (many of them are quite silly and as they describe the battle and I compare it with what I remember of the game - I can only say - you would be smashed in first 2 rounds pals!)... so I would love to challange these guys in multiplayer and check their "strategy" in real. Only MP can give this option to us.
