Yesterday the saurus got more renown (Warning long post)
A person (currently my nemesis, since i have lost to him like all our matches)from my club was up for a match, the previous losses was against a chaos legion list, which had a lot of chariots including khorne chariot cannons -.-, but yesterday he fielded a hard list, but as it turned out, beatable WoC list.
That is an awfully familiar list lol, thanks for giving it a try and posting with results, and congrats on beating an extremely tough WoC list. It wasn't the worst I have seen but it certainly is a very hard list that you really handled quite well. I look forward to you tweaking it a bit and providing more results as you get them.
As for the rules question it depends on alignment, I believe that if the DP was in the way of the pursuit move then they would have charged into him during their pursuit instead of moving through/around him to catch the warriors. From what you have said though I think even with that the game would have been yours as the DP would not have lasted a round with the TG and 2 cowboys.
And here comes the question.
Would a block of skinks with Gor-rok on the side have done equally well?
I am starting to believe that it is in fact him who does the trick.
Skinks would have probably died to the man before that last critical round or provided too much CR during that last round so that he would not have won by as much as he needed if at all. Even if saurus and skinks do 0 wounds each they still die very differently against nurgle halberds. I do agree though that Gor-Rok was key to that whole fight, one of the many reasons he is included in so many of my lists and why I rate him above other Scar Vets, I think I spoke up for him in a different thread earlier. And as has been pointed out this list is an all comers list, and with the right build and game play saurus are way more effective against other armies than skinks, sometimes not but I have just found that it is most often the case.
I really like how he used different units to support weaknesses in each other, line up the saurus to take it on the face, and then throw the TG in and try your hardest to buff them with wyssans because S6 cracks open 1+ AS units really fast, especially with frenzy 2 attack PF models

. And then use skinks to chase around things like trolls where high S doesn't mean crap, keeping your opponent on his heels does wonders for your game plan, if he doesn't have a plan B and you do can make a world of difference.
Gor-Rok Rocks!
