Thanks everyone for all the feedback Just to let you know how it went; Had a fantasticly fun weekend, I got partnered with an entire goblin army bar one BLack Orc Warboss.
50 Goblins, full netter, command, fanatics etc
2 Doom divers
6 Trolls (you should have seen my delighted face )
Black Orc warboss w. enchanted shield, potion of speed and 5+ ward
Lvl 4 goblin shaman with dispel scroll.
Our army was.... unpredictable at best. We won 3/5 games. The first one we lost due to poor deployment as we were just getting used to each others armies and the last one we lost half due to being against some very good and well deserving opponents and half due to failing stupidity and rampage tests on both the troll units and the hellcannon for the first THREE turns!
Throgg definitely got man of the tournament taking a very impressive 9 character heads in 5 games He even managed to do 11 wounds on a chaos lord which was beautiful (I love the image of a melted lord at his feet ) and he survived every game.
We actually managed to win Blood and glory somehow. We hid our general (the black orc warboss) and our only banner at the back of the board. We were against two vamp armies and everything they sent at us just bounced off throgg and the other troll while the hellcannon saved the general by holding up the hexwraiths for 5 turns.
All in all a hilarious weekend with quite alot of shouting "you stupid troll!"
