On the tabletop I mean. If you think he is great as is, awesome! This thread is for suggestions from people who think he might be a little bit lacking currently. Personally, I think he is overcosted for what he does. He doesn't add anything special that you can't get for cheaper elsewhere. Calgar plus an Lt. is almost always superior. I have two possible changes:
1) Keep his stats and abilities as is, but change him to an HQ choice that fills two slots, and drop his points cost by 15 -20. I feel this would make him a valuable choice and would make the choice between him and Calgar plus a Lt. actually a decision you might have to think about a bit, as you would still save points with the Calgar combo and you might not need Gman's melee in some battles, and you would still get adept of the codex with Calgar.
2) Keep his stats and points the same, and keep him in the LOW slot, but give him a new ability. I was thinking of an ability where he essentially gives you a free re-roll once per battle round as a way to represent his strategic ability. This would still be usable in the same phase that you did a command re-roll, just obviously not on the same dice roll.
Just some thoughts on possible ways to change Gman to make him more relevant/special. Thoughts? Also, what would you do to change him if you think he needs a change?
