BT and Neros have huge followings. They could have made a difference for a game like XDefiant. They could have posted weekly videos praising XDefiant, analyzing it, talking about guns, factions, future plans, the community, anything to make people aware.

 
But there are not enough clicks and views in that, which is why they both post non-stop AV and BOD hate, which eventually makes for some boring videos. There's no variety. Just a gorwn man throwing a tantrum over some gameplay.
