Nexus would only be a problem because the turn order is bugged, at least for Corruption. Globals aren't supposed to go into effect until after the rituals phase is over, so nexus shouldn't generate income the turn it is cast according to the book, but it will (I believe) in practice, although how much will depend on where in the random casting order it ends up. So if people were routinely spending 600 non-astral gems/turn on rituals it would be a safe cast, although it would be 1200 if you figure in alchemy since you won't get pearls from it (you get half the gems spent, and on average will collect from half of the spells cast the same turn as nexus because of random cast order. 150*2*2) I BELIEVE forging DOES happen before rituals, so the nexus caster won't be collecting from forging on turn 1, just rituals. This seems like it could happen late-game on a 1000 province map, although it is a huge chunk of gems.

I think a better solution would be to up the base cost of it, maybe to 300 pearls so that there's actually some strategy going into the gem economy equation. It'll be hard to make a profit with it if it's that hard to cast. If people can't get their stuff together to dispel it, well, they brought the loss upon themselves then, no?
