OK I just got Halo 4 a month ago and have been playing it pretty much on a daily basis. I am really enjoying the game and have been fairly happy with it. However, a few major issues I do not like and get me kind of nerd raged about. The main one is how is it that people don't even have their site on my body at all yet they have a red reticle and can kill me in just a few hits, yet when I try to do something like that I can't even hit them. This is not something that has happened once or twice. I have noticed this in several matches I have played and I even watch the kill game footage of it showing that their targeting reticle is red and my body isn't even in their cross hairs. Am I somehow missing something? I try not to get mad about it but it seems like this happens to me quit a bit especially when its a map that is like SWAT or the new Slayer Pro. Another issue I have is with the vehicles. I am quite fond of the Ghost and use it a lot and do get splatters when I am in a groove, however I have noticed even when I am going at a pretty good rate of speed in the Ghost and someone is in front of me sometimes I don't kill them I just move them to the side and knock their shields off. I myself have been killed by a Ghost or even a Warthog Splatter wise when they are barely going fast at all when it seems like I have to be going pretty fast every time to kill most people. I know that there are the abilities and what not that we gain from lvls 1-50 besides the specializations that do benefit you in certain ways. I just want to know if their is something I am missing or have yet to unlock to be able to do the same thing as them.
