I would've been okay bringing the old bosses back if there was some sense and logic to it. But OTM simply scattered them around the world with no rhyme nor reason. Plus it's overkill releasing all 5* and 6* versions just to create "permanent content" because the Fishing Update literally has none that will capture players attention longer than a month.Bringing back the old bosses was only a mistake if that was the end of things and that's all they wanted to do for "new" content.
But it's not. Bringing back old bosses and lux allows all that hard work to shine and be available to a wider audience.
They should then release permenant gear to patch up the supply of gear that gives players an unfair advantage in bossing. There was never an expectation that would be the best lux ever released. In fact all mmos have gear inflation where gradually over time the power of drops increases so only the latest stuff is the best. CH is very odd that random shop buys and drops from years ago are superior.
The Winter King in Mordris Cave? Yule Monoliths in Murky Vaults? wth is that. There should've been somewhat of a realistic/logical zone-boss relationship. Dragons likes caves, Undead like sewers, etc.
What we have now is simply a chaotic plethora of bosses to kill because OTM writers couldn't be bothered writing a cohesive storyline on what their MMO is really about.
