They should've looked at the older high level zones for monster placement instead. They keep trying to make sure you don't have to have any of the expansions to keep up with the level cap increase if you want to, but honestly, why would you need Lv90 for anything if you don't have any of the expansions?

They could've used Ro'Maeve, The Boyahda Tree, Gustav Tunnel, Kuftal Tunnel, Ifrit's Cauldron, Den of Rancor, The Shrine of Ru'Avitau, Ve'Lugannon Palace, Al'Taeiu, The Grand Palace of Hu'Xzoi, The Garden of Ru'Hmet, Pso'Xja, Uleguerand Range, Newton Movalpolos, and I could name any number of WotG or Aht Urhgan zones too. The bottom line is that it seems slightly unnecessary to place the high level creatures in most low level zones. Even in Fei'Yin, where they could've put these things in out of the way spots for the lower level quests, they were placed in the room for WHM AF and on the path to the Qu'Bia Arena - the site for Rank Mission 5-1. I have friends considering a return to the game that might need to start over, but they would be woefully unprepared to have to deal with a Lv95 Ghost in Fei'Yin for a mission they may be attempting at Lv50 or 60. Sure I might be along to help them, but what if they wanted the fun of joining other new players for a challenge? They could not longer do that thanks to this new set up.
