It seems that each tournament conditions might vary. As an example As confirmed by Mirade on the Forum for the next Tournament:
"So you've told us that Roshamuul gonna be open, what about teleport to Yielothaxes - Raging Mage world change. Would it work the same as on the normal servers or the event just won't be active and so the teleport to Yielothax respawn won't open?
Those mentioned here are the only access points that we have changed on Tournament worlds. Other area access points, events, raids or quests work like on normal worlds. " 1
"Will restricted areas such as Roshamuul be open?
Yes, Roshamuul bridge and wall, as well as the Halls of Hope (imbuing) will be unlocked" 2
