What happened was Guild Wars 2 came out and the Tyranny server virtually died. My guild, which I had been part of for two years, slowly lost its population (we started a guild in GW2 on Sorrows Furnace server). Many of our members went to Set server. I moved one of my Guardians "Ragsguard" used to be "Rragnar" and my sin "Ragnarx".
Moving my sin was a hard move for me because I love open world pvp. The fact is though, there is really no open world pvp anymore. The Red Nails were bringing it, but it became crazy with almost everyone on the server joining only two guilds = Req Nex and Acos. They have a raid alliance, so they have no open world pvp. Since Red Nails only had a couple players bringing it: Ripstart, Ty, Romad, Unnatural and myself, it was very easy to zerg us down. But....we made them pay.

I hope that there is someway to revive open world pvp. It is an aspect of the game that can be enjoyable. Maybe not when you are questing and you end up in pvp when you might not necessarily want it (but thats why you sign for a pvp server).
I'm looking forward to the new mini map, and maybe one day there will be a merge of some kind that will unite the players once more so we can enjoy open world once more.
