Okay, I've played a few games of 6th now, and setting aside the fact that the game moves slow as we all have to cross reference rules and figure stuff out, I find the experience to be mostly "meh" overall.
Playing an assault heavy space wolves army with thunderwolves and fenrisian wolves, I find the game rather boring. For example, last night I played a game with short table edge deployments and objectives. We rolled 4 objectives. My opponened placed one in a deployment zone, so I did the same. He placed a second in the same deployment zone as his first, and so I did the same. We now each had two objectives in our deployment zone.
With the changes to fleet, nothing happened unti turn 4 of the game. My opponent hung back. I slowly moved forward. I finally got into assault in turn 5. And the game ended because it was getting late.
And that's not the only game I've had go that way. Despite all the talk of big changes and chaotic stuff supposd to be happening, and narrative building, I find the game is very dull!
