Whereas in Protoss you can make one pylon for probes and another for other spells and never have to decide which to use.
I suggest that to bring the spells into tension with each other you give all the Dark Obelisks a shared mana pool. That is, when you build a new Dark Obelisk the mana pool total and regeneration increases by a set amount that can be used from any Dark Obelisk.
This means that if you build two Dark Obeilisks, one in your base and one near your opponents base, you will have to decide if you use the mana on an attack or on economy because the mana pool for the both the Obelisks is the same and will be drained by any casts you make.
One advantage of this is that you can never waste a Dark Obelisk building because they will always contribute to mana, so they can be made more expensive. Another is that it contributes to race diversity because the other two races ave nothing like this. A disadvantage is that it might be confusing at first.
What do you think?
