You guys rly dont read the whole stuff right? No store item needed for those changes(cry of dawn and r110 upgrade). Take your time to read again.
Juji said a while ago they are aiming to push changes globally to make all regions as alike as possible. We are getting updates from korea as fast as never before.
Why do they want this? Because from a development poinf of view its a nightmare to maintain different versions of a same software consistent, specially with a small team of developers to take care of it all. Korea, West, Japan, China, Singapore, plus the royalty export versions like 4game and Innova all with different demands.
I remember the frog buff from Lizardmen was bugged, the effect was not applying to crossbows after GoD update(and they had a ton of devs back then). I reported that time and time again. They would fix during some regular maintenance and when a new update came the bug came back also because they didn't merge the fix with the updates. Code was simply lost somewhere in some branch(if there was one at all). They were having trouble keeping the different code bases consistent.
Now, if that was not the case they would have never allowed the circlets of power be a reward from the newbie quests, neither have the enchants drop from Primeval Island.
They will still have plenty of other stuff to get money from if they allow easy Dragon Shirts/Kaliel upgrades. They still have the Cloaks, Artifacts, and the Wings Circlet.
