So after completing Normal for the story and having fun, I decided to try my luck in Legendary and found something very interesting.
It appears that when you increase difficulty it only really increases how much damage enemies do to you. Not how much you do to the opponents, and heck don’t even think I see an increase in enemy ranks or even more of them.
First boss fight I had used the skewer on both Legendary and normal, and the damage to his shields and health were the exact same. What he was doing to me though was clearly a lot stronger.
This actually makes me willing to continue forward as I already know when the bosses happen, what to do to prepare and have essentially practiced in normal. Making Legendary something I am fine with playing and not like the hell that was Halo 2 Legendary.
