I've done some testing lately and have come to the conclusion that Valrei is highly imbalanced in favor of Magranon. Read on for an explanation.
This imbalance can be attributed to 3 major factors
1. Layout of the map's Buff/Trap/Slow tiles:
The valrei map's special tiles are not very evenly distributed. For example, Fo and Libila are both pretty well boxed in by trap/slow/hostile tiles, while Magranon starts right next to a strength tile to start off scenarios with a significant buff.
2. Imbalanced edge crossing connections:
I checked the Wurm Unlimited code to determine all of the possible edge crossing connections. To my surprise, a lot of them were 1-way only. After drawing all of the connections, it became apparent that Magranon has a much wider range of connected tiles that he can access from his edge of the map, as compared to either Fo or Libila.
The result of this wider spread of edge crossings is that Magranon can access more tiles in fewer moves than either Libila or Fo.
3. Imbalanced deity characteristics in the new combat system:
The starting stats for the 3 main gods are imbalanced, highly in favor of Magranon. This was very easy to test, as the Wurm Unlimited code has a method for simulating fights between gods for testing purposes. By simulating 1,000,000 fights between Lib v Mag, Lib v Fo, and Fo v Mag, I was able to see that Libila and Fo are fairly evenly balanced, but Magranon is stronger than both Libila and Fo and has a win rate of about 60:40 or better versus either of these gods.
1000000 fights completed between Libila and Magranon.
Libila won 39.1482% of fights, Magranon won the remaining 60.8518%.
1000000 fights completed between Magranon and Libila.
Magranon won 60.8139% of fights, Libila won the remaining 39.1861%.
1000000 fights completed between Libila and Fo.
Libila won 50.782% of fights, Fo won the remaining 49.218%.
1000000 fights completed between Fo and Libila.
Fo won 49.6064% of fights, Libila won the remaining 50.3936%.
1000000 fights completed between Fo and Magranon.
Fo won 37.014% of fights, Magranon won the remaining 62.986%.
1000000 fights completed between Magranon and Fo.
Magranon won 63.1285% of fights, Fo won the remaining 36.8715%.
In summary, Valrei is in dire need of rebalancing.
The map layout and edge crossings favor Magranon. This could partially explain why historically MR/Magranon won valrei most often.
With the addition of the new deity stats and combat system, Valrei has become even further imbalanced in favor of Magranon.
