I vote for yes, mostly because it's a nice theme. And pretty pictures too!
Mictlan mages are totally different from the LA Atlantis UW mages. LA Mictlan cannot build national troops underwater, they just get the Rain Priest and King of Rain, plus the cool frog glaive sacreds.
Losing the cheaper N2B2H3 Priest King actually hurts Mictlan against Ermor IMO. I'm in an MP Ermor/Mictlan war at the moment, coincidentally. I need the Priest Kings because, first, I can't afford the Rain Kings, and second, without the N2 my jags would be starving. I was forced into an early war with Ermor because of geography. Damn you, geography!
Or am I missing something here? I mean, I tried building an underwater castle as LA Mictlan and the option's just not there. I can hire PD underwater, that's it.

Oh, crap, now I finally understand the poll. I need my vote back!
I thought a 'No' vote in the poll meant to take away the Rain King etc that's already in LA Mictlan. Doh.
I think LA Mictlan is cool enough as it is being able to hire those ex-Atlantian rain dudes. I don't think they should be able to hire the Forgiving Father etc underwater, because I think that'll steal some coolness from Atlantis, like, decreased diversity.
Gimme my vote back! Argh. Stoopid butterfly ballots.
