I often wonder what constitutes been a noob actually.
I have about 31 hours of multi played on reach and have managed a 0.85 k/d to date.
I just play ffa rumble pit as I find team death match a disaster.
You mostly get players dropping out which makes it totally unbalanced.
I just play the way I can play and if others dont like it well tough luck.
I mean it seems to me some folks play a certain way and expect everyone else to do the same.
Part of the fun is the randomness each match brings imo.
I enjoy reach more than mw2 which was my first game to really get stuck in to multi.
Maybe it is easier than 3 as the op says but I am finding it to be very enjoyable and if I constitute been a noob well so what really.
If other players are as good as they say any noob should not be a problem for them.
(Depending on what a noob actually is.)
