I had recently painted up some extra Goth infantry on half bases, these were added to two of the other Goth warbands giving them six bases. We adjusted the rules accordingly, giving the Goths an extra two D6 in the first round of close combat, this would give them some initial humph and sustain the unit in the next rounds. This would offset some of the Roman superiority as they get more combat dice in continuing rounds and better saving throws 4 - 6 as opposed to the Goths 6. It did not help in the end, next outing we may let them add the extra dice in continuing rounds.
I was too engrossed in the action to take any pics I'm afraid but here are a couple of shots of the forces as they stand, I currently have Roman cataphracts on the painting bench and will follow these up with another half base of Goths to increase the third warband.
Edit - Here they are, weird. Thought Jon's comment on my previous post would appear, but alas no. Thank you for the comment Jon, I got the email notification. I believe our mutual friend is having some "renovation work" soon :~)
