The trailer is really good, I just think that you should show more of some builds instead of just saying "insane pvp" because most servers probably have the same. It's gen buckets by the way. And you should mention something about daily koths Work on your timing when the text appears, you have basically no info in the first minute of the trailer and just overload it at the end.
I like the whole theme you've got going on. I personally think you should add more information in the beginning of the trailer, like Nick said. Also, show more of the factions side of the server. The PvP part you did is awesome, but it'd be great for viewers of the trailer to see more bases, cannons, etc. I think I'm not making my point clear enough, but you get what I'm saying, right?
