How does dominion theology affect eschatological views? How do the eschatological doctrines of Charismatic or Pentecostal groups that hold to dominion theology differ from other Charismatic or Pentecostal groups (e.g. Assemblies of God) that do not?
Overall, there is no absolute consensus in eschatological views among Charismatic adherents to dominion theology. If a particular group decides to teach eschatology at all, they often teach all the main threads of doctrine and let people learn on their own. Dominion theology, in effect, could fit in most of the popular eschatological timelines.

To use the Assemblies of God's doctrine as a starting point, though, I will compare with some popular eschatologies in the dominionist camp.

Looking at the AG's site, it is evident that they believe in a pre-tribulation rapture. This is a doctrinal point very often argued against by adherents of dominion theology, because of its tendency to create a defeatist attitude among believers. In the dominionist's view, the Kingdom is always advancing towards its ultimate fulfillment, and there is no need for God to remove us from the earth during the Tribulation. God will be doing great works of which we will be a part, and the Church will never give up on influencing the world. For some dominionists, this would mean a post-tribulation premillenial rapture (see IHOPKC's Omega Course).

Other popular eschatologies that fit very well with dominionism are postmillenialism and amillenialism (postmillenialism being a literal interpretation of the millenium, and amillenialism being a symbolic unknown time period). In both, the Church is advancing the Kingdom of God and preparing the earth for the second coming of Christ. The "tribulation" here is figuratively interpreted as God's judgements along the way, of which we participate, as the Church takes complete dominion of the earth for God.

See the book Victorious Eschatology for a little more on some of these views.
