They tried to replicate battles with a game that is entirely incapable of supporting the on screen character count required to do so. Defense of (spoiler) is a great example, the attack is simply three or four enemies at a time, It's pathetic.
Beth should have worked within technical limitations and gotten creative. Since you're treated as a special forces type working alone or in a small squad they should have focused quests on things a squad could accomplish, sabotage, hit and run attacks, assassination of officers, and given the illusion of a larger conflict on going. It's just ridiculous they send you off to take on a garrisoned fort head on with 4 or 5 friends, really?!
EXACTLY!
People are complaining about the college quest line but this is worse!
How about sending an agent, someone who does not belong openly to the legion or the Stormcloacks, to assasinate a Jarl? What about penetrating in the castle/fort vault and steal the soldiers salary or destroying their food reserves (or poisoning their wells with the corpse of an animal) ? I can think of dozen of more intriguing missions for an individual who is recruited for his/her talents.
