a trailer should be: what fgunz offers, the clothing, maps, the activities you can do at fgunz, the community (events, funny clips, colorful maps, custom things fgunz offers). The action is just to ignite the feeling to also frag at fg, a trailer isn't slowed down footage of maps, nor frags. It must be a well put together marketing scheme to convince the viewer that the product is good enough to try out but then the product itself must be good enough to keep the player hooked.
Look at your trailer from a perspective of the viewer, would you want to join that server after watching your trailer, if it feels like something is missing, what is it? Look at the V7 trailer chef posted (https://player.vimeo.com/video/116441622), you can see that the trailer showcases what fgunz offers, what gamemodes, it shows the community, it shows how much fun a player can have at fgunz, after watching the V7 trailer back in 2014, I instantly downloaded fgunz and got hooked, that's the magic of a good trailer, that trailer made me WANT to experience what was happening in the trailer.
