Don't like the lock boxes, never have, the have been tried time and time again over the years of Aion, the main purpose seemed to be selling keys.
I am ok with poor open world drops, as long as the stuff we use to get from it, is available from instances or vendors. eg. In later Aion, many of the dropped blue recipes could be bought from NPCs outside the crafting areas in Sanctum or Pando. A large range of stigmas could be bought from the stigma tuner. I don't see why these two ideas from later Aion can not be brought into Aion Classic too.
