I felt the same way in the end. I mean it felt like this massive legion army just never materialised. I guess due to engine limitations, but then again other limited game engines have achieved a grand scale using waves of enemies. Oddly enough there is reference to the Legion using such tactics of wave after wave of enemies, that's what I was expecting in the final fight :/
The biggest threat the legion seemed to possess was superior numbers, the game didn't pull that off imo.
The Legion infiltration on the other hand did feel right, they seemed to have spies in all the right places and had me wondering who might be working for the legion.
