I hope the generic reloading animations will be replaced with proper ones, and to adress the problem of reloading heavy launchers on the move, I have the following suggestion.
-Make it impossible-.
Drastic, but here is the Idea.
When reloading a Titan MPRL, the player will go into kneeling position, place the tube on the ground, and snap the Launch control unit onto it, and then shoulder the launcher.
IF the player MOVES, the Launch control unit goes BACK into the Inventory. The Launch tube will remain on the GROUND.
This will force players to think about when to reload a launcher, but also will not kill them if they accidentially hit the button in the wrong spot, or need to move when surprised by an enemy while reloading. They then have to fetch the ammo back from where they dropped it.
Make the optic/Launch Unit the weapon proper, and make the disposable launch tube the ammo.
When player launches the weapon, the tube is empty and will be discarded, and the optic/launch unit/trigger assembly will be stowed back into the gear.
Also make the LCU for the Titan, for example, the weapon/optical part and allow unloading it to use it as observation device.
