The entire server was shook up , the update notice was massive. No one predicted this sort of update to come soo suddenly.
Usually games have small updates and a gradual shift in features , however Omega launched such a massive upgrade at once . It was hard for the player base to adapt.
Actually a part of the update had been predicted by various experts that there must be a massive map upgrade. Because the levelling grounds only housed monsters up to level 60 , there were no higher dungeons available either , for the current player base , level 60 seemed to be the max limit.
The maps around the cities had varying difficulty , soo unless the monsters became stronger there , there was no future path of progression. However the monsters could not be upgraded in strength as there were still a huge playerbase , that needed to farm for exp in those grounds.
Hence the only option available was map expansion.
