hey, i'm new to
40K and i just started platying a month ago, i built a 1000 point Tau army only to realize they are broken as can be so i'm going to keep playing with the tau and trying to improve, but in the mean time i'd like to win some games so i got the following list. i already have all of the units and really i'm just looking for weapon/wargear and general setup tips. if you feel an
HQ other than the one i have is superior, please suggest one, as i wouldn't be opposed to that since they are pretty cheap relatively. thanks in advance guys
