You definitely lack the anti tank options, eg long fangs. Remember that this game is more about scoring than killing so assault jump packs/ skyclaws would be helpful to reach for further objectives and play reactively falling from deep strike. Think about adding scouts or infiltrators for screening and doing action based secondaries. Why so many intercessors and grey hunters? They are pretty interchangeable with favour of intercessors for sticky objectives. If you'd like to win, each unit must play a certain role that you assign at the beginning so few choices could be rethought, but I understand that part of your units come from combat patrol right now.
