I think the problem with the Dendrobium is the fact that aside from the beam swords at the bottom and the large cannon, it doesn't have any other 'reliable' weaponry for constant combat. Once those pods are used up, there isn't much else for it to use, aside maybe for the beam rifle that also comes in the compartments. I think it should have had some other moderate weapon build in to take care of grunts without having to expend the canisters so often. Or perhaps being able to set the beam cannon to a lower output like a rifle or perhaps a 'beam shotgun.' also... guy was an idiot for getting his i-field ripped off....
