Hmmm the ultramarines tatics are weak, being 1 time use but no one should complain. At least it will be used compared to tge current chapted tactic. All the other tactics are really strong for something free.
The traits.....i see 1 good one and thats number 6. A d3 extra points can win you games
And last, the hunter tank sound very good now. For 75 points, id take, keep it in reserves untill enemy flyer comes. Cause 90% of people will have something that flys. And with the savant lock rules, only helldrakes and monsterous creatures dont worry about it, unless jinking doesnt count as a miss
