I want to discourage this sort of behavior in these forums. Us gaming channels need to help each other but not by sub4sub. We can watch each others content, and if we genuinely like what we see we should like and subscribe to each other. Its also about thinking long term. Don't try and rush a sub count, your not going to get anywhere overnight. Take it steady, and pass the pebble on.
I'll lead by example.
ICYYY, I watched your BF3 content. I quite enjoy Battlefield so thats a good start
Your videos were of good quality and you showed some skill in the editing department. My criticism would be music instead of commentary, but that is down to personal preference.
Peanutbutter, I watched your latest Technic Pack Minecraft video. I have played Tekkit and vanilla Minecraft, so I've got some background knowledge. Off the bat you have an objective that is being achieved in the video which is something I don't know how to do. You showed how to make the nano suit armor (along those lines). Your audio was of good quality as well. My criticism would be your use of annotation. In our own videos, we do add an annotation asking that the viewer subscribes, but we put it at the end, and try to make it fit the text. A new viewier will let the one pointing to your sub box above the vid pass but I'm not sure whether a big yellow box that takes up a large section of the page at the middle and the end of the video will prompt them to do so.
Hopefully I've offered you some feedback you can use. If it has helped, I would kindly ask you to take a look at our channel and help us in return.
Otherwise, I agree with Slingly.
