I am currently umming and ahhing over my 250 points for month 3. My initial fancy is some Fire Dragons in a wave serpent. I can use these to whizz about and soften up monstrous creatures prior to any assaults or get round that pesky "we'll be back" rule. I can use the Wave Serpent to contest objectives at the end of games so seems like a good choice.
However I have also managed to get hold of some war walkers which I am assembling. I am wondering whether 3 war walkers with scatter lasers might be nice as well. That would be 24 S6 shots per turn coming out of them....hmm decisions decisions
