Might do another top 12 but I want to see Zen Shadow try one also.
I'll take a stab at it. Should be an interesting exercise. Haven't done one for a year or two.
1) Mayhem et al. - Swim -Spanning 5 oceans with 6.4 million points and high fighting ratings.
2) Mummy et al. - Swim - Spanning 4 oceans with 5.9 million points and high fighting ratings.
3) Infernal et al. - Swim - Spanning 3 oceans with 4.1 million points and high fighting ratings in their main alliance.
The top 3 alliances are the main core alliances. O44 seems to be where they all meet. I would expect wars and rumors of war between these large alliances for control of the core oceans.
4) Heroes - Swim - Controlling O64 and expanding into O63 with 1.5 million points and respectable fighting ratings. May have Mayhem pushing east, so we will see how they fare.
5) Viridians - Float - Based in O46, a respectable rim alliance with 1.2 million points. Have Mummy to their north and other alliances interested in O46.
6) Enigma - Float - Based in O65, currently sandwiched between Mayhem and Heroes with hungry rim alliances south and east of them. 1.2 million points.
7) Elysium - Float - Based in O56, decent sized rim alliance. 1.1 million points, probably will see challenges from the north and the other alliances with significant presence in O56 such as Enigma.
8) Drunk et al. - Float - Based in O65/O75, spanning 3 oceans. 1.2 million points between 3 alliances. My alliance, so I won't comment further.
9) Millenium - Float - Spread over 4 oceans with larger alliances around them, but far enough from the core for a float. Part of the mess in O56.
10) Heavenly Kingdom - Sink - Based in O43 and will likely be eaten by the big core alliances.
I think I'll stop at a top 10. There are other notable alliances, some with few players, but high average points such as No Stress in O63 and REPO in O52. However, they will have to grow or merge into a bigger alliance to go the long haul. I believe the top 3 alliances are here to stay for quite a while and we will see numbers 4-9 in the rankings for the immediate future.
Big wars are likely in the Core Oceans, particularly O44 and O55, and the focus of smaller wars seems to be in the O56/O66/O65 region as there are many alliances trying to carve out a base in these oceans.
That's my simple top 10.
