they have way to make content with replay value, the question is do they want to spend time on making them?
a lot of player have told them that they want content perfectly balanced and such... we did say for long that scripted content was plainly bad and was needed to be changed!

the trouble, as i have told, is the lack of content to the same level of reward than raid and dungeon (that are often heavily scripted and with a replay value near 0) they need to add activity that can rivalize with dungeon and raid in terms of challenge AND reward! mmorpg is not a dungeon like game type.... they need to make us feel part of the world. after we did complet the story.... we are disconnected of the world and that one trouble they need to work on.

hamlet defense from the V1 was a try to change this, it's not perfect and can't be reused as this, but the idea behind is interesting. i hope they will go in this sense for when we get closer of the war with the empire. making us needing to fight for protect area from the control of the empire. pve interaction don't need to be left into dungeon, they can even take different form... they can even try to look at the fps genre for create new content.

some idea is a horde mode mixed with the domination the player must keep control of area while fighting wave of enemy! it can be done perfectly, they can even work on a system making the encounter random like the splatoon system making map only avalaible for a time of period. the point of this sort of content it's not that hard to create map for this... since the enemy can be divided between faction like the tribes, the empire, the dragoon or even bandit/pirates! when a faction is completed they can add this to the system while continuing to add new map. the point is to make us part of the conflict roaming around.

like i have said they can add a system of reward taken from the pvp, with grade earned by the participation of the player, a token system that are used for buy new gears from it. other advantage, it will offer the capacity to choice the type of gears we want to equip. instead to have everyone wear the same equipement at max level. more choice is what they must work on!

it's only one type of idea, you can do anything you want, that the forte of the mmorpg, nothing is impossible the only limit they have are the one they create themself! another example, since a looot of people like speedrun, why not create a system of time attack with a leaderboard, same different token for get different type of item. the point it's to reward people deciding to spent time into one type of activity based on the time and effort spend into it.
