Season 5,6,7 Pvp Weapon

On the realm Lorderon i cant find any pvp weapon vendors from the old season and i dont know why, the vendors for season 5,6,7 wher removed in cataclys not on WOTLK. The seasons work on Retail becasue after all the seasons end you get a new expantion or new gear all the time on a privare server you dont have any of that and you cant delete ppls items and make them start from season 5 and all the way back to 8, is this a feature for the server because it is a bit hard for a ret paladin to farm Trial of Champion Heroic or Pit of Saron Normal for a good weapond drop... PVP is hard with joined battlegroup wher the other have the ability to buy weaponds from the website.
