Mythics answer to this, in their unique free expansion program, was to create a completely new frontier with the TOA graphics upgrade. This new frontier did away entirely with the old frontier, adding new styles of keeps, which not only looked better, but were more interactive, instead of just the doors being attackable, you could actually destroy keep walls, mount siege weaponry on the castle walls, even hire various npc’s such as mages and rogue type npc’s to help defend the keep in addition to the normal guards. You can now port directly to some of the keeps instead of having to run across the whole frontier to get to the fight, you can also take boats to get you there faster. The keep fights are much more involved and interactive now. There was even a realm war map added that not only let you see where you were in the frontier, but would show you where heavy fighting was taking place.
