Good guide
some points:
- At the endgame astral income is dirt cheap. It may prove difficult to maintain your globals then.
Also with this tactic you'd have to protect your pretender extremely well. If he dies in battle or get assassinated the globals are down.
This global route makes me nervous. I'd personally stick with playing this nation treating CW as a nice to have bonus.
- Army of lead can not be used all the time with impunity. Go that way and you'll soon lose your armies to teleporting wrathers.
