1. At rest, or idle, animations for characters, with and without weapons drawn. Possibly even empire or weapon specific stances and run animations that are toggleable. For example, the TR, being very traditional military forces, would carry their rifles down in front of their stomachs. The NC, being very laid back about their soldiers activities, allow their troops to hold the weapons one handed by the grip, over their shoulders or just hanging down to their feet.
2. Decimator "reload" animation (after firing and waiting for the next shot), both for the player and the person seeing them. If theres one in the game, I've never seen it.
3. Visible holstered grenades. I just don't get why you can only see them when they are equipped.
4. BFR pilot weapon aiming causes the torso to twist, rather than changing the facing of the weapons. Also, only the BFR feet angle when walking on the sides of hills: the torso stays at the same level of "roll" at all times (Yes, these ideas are from Mechwarrior
). Where exactly are the BFRs' center of gravity?
