The last one was long and painful because of the character mortality. I lost Callandor in Enweil during a large monster battle along with 3-4 other nobles, which made me decide not to rejoin BT for a short while. I'm actually looking forward to another invasion, seeing as with the new estates system we will be able to expand into the blight quickly, if there aren't a huge force of enemies of course. Also, all of the realms on BT are connected at some point to the blight.
You're assuming that the blight will be accessible once the next invasion starts. Personally, I do not believe that this will be the case. We mostly lost the last invasion. The blight is the price we paid.
