After a couple months of playing Halo 4 I have come to accept many of the things I didn't initially care for.
I missed betrayals... Didn't like that if I'm in a melee fight and an opp rockets me, his teamate gets to walk away fine. I'm over that now.
Didn't really like any armor ability.
But there is 1 thing i still strongly dislike
If i kill a guy i can't picknup grenades from his dead body. Why the F do i need to waste a tactical package to be able to pick them up? Very unnecessary. I hope for Halo 5 grenade pickup will be le all prvious Halo games.
