I think the point here is this server focus on a good old time with cabal. Well I have played some p-server, some of them add too many change, that's not even cabal anymore: most of dungeon are useless, player can only farm in few spot, too many new (and weird, imo) stuff, character are unbalance, crafting nearly not exist. All you have to do is farm, get an end-game gear, and nothing much to do but TG. That's kind of boring for me. Some server are actually good, like Elitecabal back then, but it's a low rate server (well I have to play for quite long for Mystic BL 7% amp set). OGN Cabal are good too, but the farming process are so boring (you have to do daily quest for end-game set, and if you want it fast, do it with 6 character a day!). I haven't try on Beast Cabal, because personally I don't like the idea of rebirth/reborn.
I remember when cabal have many feature to explore: dungeon, crafting, quest, hunting. The reason that I play p-server is to enjoy all the feature of the game (which I can't in official server, damn, how long to get a fricking dual-amp Archidium or max-level craft), not to explore some this-is-not-even-cabal things.
One more thing, reading about chronologically releases make me remember the progress I have back then. So I'm really excited to start over again xD.
Well it's my opinion, sorry if it's too long (and sorry because my english isn't good)
