Psychology mods? Increasing the role of troops?

[KnidVermicious]

Well, that's how I envision it. A suicidal bomber runs up to the enemy and blows himself up (destroying the unit) and hopefully taking some enemy with him.

Does anyone else think that planetary assaults/ground combat should be a bigger part of the game, or is it just me? Not to say I don't enjoy slagging a planet, but I also love the thought of my space marines dropping on a planet. I want the ground combat side to have more flesh, I guess.
