There is little clarity as to what is going in combat. Enemy troops (and some of yours) will have arrows in differing colours, but mostly no health bars unless you hover over someone. Everyone starts running into and through each other, with no indication of what side is winning. At one point I though the enemy were dead and it turned out they had a dozen or so left.
One creature description has already been unhelpful. "can keep our enemies off-balance" means they get flung in the air.
