So then the Xel-Naga would be unstoppable, if there spawn time would be better then say a zerg...

What happend tho is the zerg evolved so fast in SC, they whiped out the Xel-Naga in a matter of a few years after they were created. If anything, What kind of plan do you think the Xel-Naga will have in rebuilding there own race... I mean seriously, the zerg defeated them when they were in there infant stages.

The point I was getting at in my above statement was... what could the Xel-Naga do in a 10 year Period, that would make them strong enough to even think about an offensive on the zerg or any race for that matter. I dont know about you but I belive the book on starcraft said the zerg completely destroyed the Xel-Naga. Now put that into context, did you see Hitler planing WW3 after we the "Allied Forces" Kicked his @$$ back to the stoneage in WW2?? No, Germanys economy is still today recovering from that... and we forked over a ton of money to get them rolling again afterwards. I dont know if this even makes sense to you but it sure does to me
