Right now the bandages are unlimited, it's actually a one handed item rather than a throwing item. Most likely we'll be restricting it in some way but we'll need to do some testing to figure out what would be best for game play. On the last thing, I assume you're talking about the French 75's hydro-pneumatic recoil mechanism. I'm pretty sure Dany can make them behave differently and remove the roll back sequence for the 75. If you want some extra info, we haven't focused too much on field artillery yet, however, the ramrod sequence has already been removed and it is now loaded from the back. I believe the mortar drop rate has been untouched.
I don't want to delve into how our class system works just yet. More information will be revealed in the future.
Edit: @Landrik. On the destructible trenches; it's unlikely that you'll see them, at least for the first release. It doesn't work well with our trenches and would take a lot of extra work which will delay release. The shovels are indeed being worked on, along with all the scabbards.
