i have both cl and gh crafted houses and the to ones from both mega bundle packs and i noticed that they all have private dueling rings in them but the gh house does not. its sad because the watch tower hall is my favorite house but has no dueling ring AND i know a perfect spot for it. on that ledge on the side of the cliff with a bunch of wooden stakes around the edge on the rite hand side of the property. it is a PERFECT spot for a dueling ring only the cave sealing could be raised up just slight so some taller spells like helephant dragon efreet ice giant storm lord stormzilla kracken and other spells would not bump there heads on the rocks OR make another cave tunnle inside the house in the room on the left hand side agacent from the room that has the tunnle that leads to the ledge.
