Interesting report as always.
Also interesting army. I am not a great fan of multiple war walker formations. The problem is that they are very fragile and work best in cover. They can scare armoured formations from ambush or the gate, but otherwise tend to be targets for virtually anything. One is fine as a screen for the titans.

I understand the temptation to increase the number of singleton Revenants, but suggest this should be resisted at least for now.
