That's only based on opinion, I however don't think that the server features particularly matter about the population of the server. People care more about having a good map rotation, a leaderboards system (this will benefit DR, apologies if it's already in the mod) to give people something to drive for other than just the regular unlockables. Take Blur, IceOps (who were which still very popular up until @iiManix and I), TwS, and JoKe (to name a few); they all had no particular features which stood out, no exclusive maps, weapons, assets (most literally had an edited hud, however Blur was default) yet they were still popular and I believe it's due to the dedication of the owners at the time, there just isn't the dedication anymore due to the decrease in population of CoD4 DR in general. What I'm trying to say is that if Raid (in my opinion) want to stride back up to the top then it's going to need a completely new approach. As far as the mod is concerned, I don't think that's the problem at all as to why there's nobody in Raid, I believe it's to do with the contributing factors I have previously mentioned. Also, about the map rotation I don't think there's much which can be done with that either unless some sort of community poll was made (even then, would be pointless because there's no community to vote) or if someone took charge and found the most liked maps of deathrun and put them in the rotation to have someone actively working on the map rotation then that might bring a fresher feel as the same maps won't be played over and over.
