LA Pangea - a rotten way to go green

[Finalgenesis]

is lvl 0 CW overpowered for EA and MA Pan? I kinda like having CW as an optional "mode" for Pans you can switch to, though thematically I suppose it fits most for LA and maybe a bit for MA.

It seems that if CW is put at lvl 6 in ench tree for EA & MA, it might as well be removed from the spell list for those ages to keep with the theme. I'm guessing the intention for lvl 6 research is a theme adjustment rather then balance consideration?

I'd say 50 cost for LA and 90 for EA MA keeping it all at lvl 0 seem to be fine balance-wise. Unless there is something broken about it for EA MA that I'm unaware of, otherwise my gut feeling is that it'd be a shame to cut off alternative flavourful strategy for nations (well... or lower it's viability when it wasn't overpowered).
