I think a gladiator arena or more should be added that the player can fight in for a capaign mission to start with then come back for rewards. you could start the play as a prisoner for the mission but then after they have won their freedom they can come back later to win fights for rewards like new weapons and armor and gold.
Also you could make a jousting tournament arena that the player can enter when he/she wishes to win rewards to use inside the arena and outside.
And make actual jobs the player can do both basic rping ones and fun ones such as being able to be hired as a city guard or an escort or be a servant or whatever.
also the dragons are fu nand all but they all look the same when your lv81 unless you go to a special area so make a variety of ancient dragons so your not always fighting the same one wherever you go.
But before any content updates please fix all the glitches that stop gameplay or questlines in its tracks before the glitches no one cares about like exploits. its up to idiots to ruin their game or not by cheating so pioritize bugs like the famous theives guild bugs that stop you from even joining it and ive heard others that stop you from even continuing later on.
And fix that other famous glitch that when the player obtains a random book (or other random items that happens to be a quest item but the player doesnt know that at the time) and the player gets the quest to retrive that item later you can give the item to the quest giver right away and complete the quest instead of being stuck with the quest item forever and never being able to continue.
