idbeholdME: I wouldn't call anyone sending death threats over a game a fan of anything. Mental is the only thing that comes to mind. Let alone people who call themselves "fans" but have no idea that the series had sci-fi elements in it long before that.
But they got what they deserved. A rushed town with 4 recycled units and one of the most imbalanced factions in the franchise history. Good job, "fans".
I don't see any relation or logic here; it's the same as saying that Britney Spears (or insert any other pop music star here) has no fans because some of them (call them whatever you prefer, the "evil people" for example) issued death threats to her, or that there was no criticism for the new payment policy for the Unity engine license because someone threatened them with death.
I fell in love with Heroes of Might & Magic since the very first game in 1995, and before that, I enjoyed playing the King's Bounty (1990) game. For me personally, it was a pure fantasy spin-off settled in a parallel universe. Those screenshots with new faction units from the local gaming magazine were hideous and completely out of place. At the time, I had absolutely no power to declare my dissatisfaction by any means.
Given how things unfolded afterwards, I wish they had developed the expansion as intended. That Conflux faction is an abomination, except for the Firebird.
I'm still eagerly awaiting the final campaign part for the Horn of the Abyss mod.
If I could, I would tell New World Computing that the upcoming Forge faction looks meh, and I consider myself as a fan of Heroes of Might & Magic, the spin-off series. Your point that the original Might & Magic lore is vast that it includes advanced technology and space traveling among other things is solid. However, it's important to note that there are fans of the original series and fans of the spin-off series, and they don't always mix well together.
