How is LA R'yleh overpowered?

[Kuritza]

1) The only LA nation with an unerwater start. Some LA nations can get underwater, but hardly compete with LA RLyeh there.
2) Tons of free spawn, some of which isnt 'chaff'.
3) Mind blasters, even in PD.
4) Highest astral of all nations. Up to 5, actually.
5) Dreams of Rlyeh, one of the best assassination spells around.
6) Insanity domain. Hard to fight Rlyeh when half your commanders occasionally decide to dance around some tree chanting Rlyeh Fhtagn!
7) Mass prophets.

Rlyeh has domkill now, but all of the above is still true. Maybe not 'ridiculously OP' now, but still pretty much OP in my opinion.
