they were made to be annoying for players of TFU more like the only attack you can do that is slightly good against them is force lightning (since your saber is next to useless) and that takes like 5 blasts until they fall down, they're a bit like the brutes from Halo 2, there are no interesting attacks/movement or deaths and is essentially a damage sponge. I think they were probably added in late to make the game harder and add some slight variation to stormtroopers but they really just killed the pace and fun of the game
