So, I took a look at your channel. Noticed a few things actually. The first being that I cant access your "about" Section of the channel, In fact I cant access anything in the channel besides the front page. Not sure if this is because of the account i was using, or if it was because if your channel settings. Most likely the latter. As for what to do in Toribash, The one thing that EVERYONE goes to is the Replay Showcases or things involving replays, so if you stray from anything involving replays, that are not your own (because showing off spars that you yourself made is nice), I feel like you will bring in more viewers.
It wouldn't be "stolen", Done before? Probably plenty of times, but its not something that someone is known well for. I would try It and see if it takes off. It also depends if you want to just want to show off the match or give your reactions to them. Just showing them off is easier one the person making the video, provides less edits, and you usually don't have to say much if anything. Reacting or commentating them means talking alot, more edits, but more people tend to watch those videos.
As you know I'm a realism freak, how about a top 10 tricking/parkour or sparring series, I haven't seen that.
Being that ABD is a seriously common mod it would receive a considerable amount of attention!
