I think most gamers here are having trouble getting noticed, me being one of them of course. But quick glance at your channel and you seem to be doing better than most, you've only being doing YouTube for a few months and already have just a little under 300 subscribers. Nobody gets "noticed" in such a short time. It could take years before you start seeing a huge amount of growth in views and subs.
One critique I have though is some of thumbnails just being attractive females.....for a Black Ops video.....don't use misleading thumbnails.
