Event sugestion:world boss atack

Eolos - Raging Tide

Hi everyone,

I have a event suggestion for a weekend of fun, we have these super bosses like sonic oppressor and others just lying around doing nothing and waiting for a courageous group to go kill them for their drops....

...well the story of the game says there's a war between the races and the wraiths so what if for once these bosses took matters in to their own hands and lunch an attack against a major city in the game?

this event could have or include:

-a reward system for damage such as nien beast event.
-a "defend the castle" or "siege" in which the players fought the boss and its legions from inside the cities in the walls, which ofc must have a ranged type mobs for ranged classes and ones with the ability to climb the walls (ladders/flying) for the melee classes.
-the boss could not cross a certain line so it wouldn't get too close to the city otherwise habitants would die and we don't want that, if the boss crossed that line event would reset and none would get their reward, this ofc implies that the boss would be the last one to show up for the action...

I hope you like my suggestion and it can be done cause i think it would be fun.
