I recently played an 1850 point game against the new Tau, with little LOS blocking terrain. By the start of my second turn, I'd lost almost 1000 points [ The initiative was stolen, and I'd deployed aggressively
Thankfully, we had to call the game at the end of the 5th, and I still had 2 Assault Termies with a Librarian on the table.
I tied the game, 'cause Maelstrom.
To the list, the only thing that comes to mind is that I prefer Assault Cannons to Cyclones. Otherwise, it's terminator heavy which I've always had trouble making successful, though I've never tried Dark Angel variety, which seems to give a little more flexibility, which might work out better.
