1. Make old nyzul and assaults use army tags that are separate from the tags used for new Nyzul.
2. Let us store up more of them than we can today.
3. Add some new cool stuff to buy from assault points.
4. Reduce entry requirements from 3 to 2. I say 2 because SE seems to think it's important that we can't do it entirely alone. This is sort of a compromise.

With these changes, I think most issues would be taken care of.
