Regardless with buff, is it possible to reintroduce the other units again for the sake of variety of characters model in the game? Such as with arty train or flag bearer.
As Max has said earlier and as I recall by myself, I think you can spawn in as an arty train without the horse itself. And regarding flag bearer, I think I've played somewhere quite long time ago where you can actually store your flag in your inventory, instead of completely dropping it on the ground when you swap weapons.
And would it also be possible to, instead of despawning flag shortly after it's being dropped, remove the flag itself as soon as players pressed 'G', or whatever dropping weapons keybind they have?
