i find the first level to be the hardest, of them all
Really? Hahahahaha!!! You gotta be kidding!! The first level is the most easy level. Fighting the final boss is the thing you gotta be scared of!!
legendary isn't easy no matter how use to it you get
That's not true. Every time I play Halo 2, I play on legendary. A few times I choose Heoric. Yes, I lose a few times on legendary, but it's not that hard
