I'd prefer if your alignment was largely based on your actions with the starting magic choice being secondary. If death always equals evil and life always equals good in Elemental I'd considered that an uninspired solution.
The game however is still a long way off so beta testers could manage to persuade the devs to change course on a number of issues. I'd personally like to have the option to pick any starting element for my Channeler opposed to life and death always being innate.
In MoM it was simply the smart thing for the AI to do. Death magic had almost no friendly, helpful spells at all. It was all about death, often on a mass scale (Death Wish being the most extreme example).
There really was no concept of "good or evil" since in the end all wizards were vying to wipe everyone else out and be the last man/woman standing.
That being said, I wouldn't mind seeing a big improvement over MoM's very simplistic (and exploitable) diplomacy. Coupled with the poor strategic and tactical AIs, diplomacy was the weakest aspect of MoM.
I wonder if there will ever be a thread here that goes an entire page without saying "but MoM did this!"
Well, that's not what this is.

Someone is making a mod to do that, IIRC.
I would be that someone. I have an interest in making sure it is possible for the mod to match the original MoM as closely as possible. Ensuring that the mechanics of the game are similar to MoM goes a long way to achieve that goal.
