...And wanted to provide feedback! Better late than never.
In all it was a very, very enjoyable campaign. It makes use of the new mechanics very well, but I'd have to agree with others in that future campaigns should focus on individual factions.
As a framework for the Dawn of War story moving onwards, this story was great. In terms of the prophecy bringing the 3 characters together, it makes complete sense that this campaign was shared between the races and now, with the prophecy over, it's easy for Relic to take it however they want. Whether they go back to the world map of Dark Crusade or focus on narrative journeys is completely up in the air.
The last level is a TESTAMENT to how good a Last Stand (Or even co-op) would be in DoW3. Throw in a new gear system, some hero-specific doctrines and make a ridiculously customisable TLS 2.0. The game is ASKING for it.
The story was very simple, but it was short and to the point. The focus was playing the story over watching it, and I'm always grateful for that. Some levels were a little uninspired but the good ones were REALLY quite good.
Looking forward to the next chapter. Hopefully it'll happen.
