The thing is, even with all of our input there are many that feel that since you're not playing the game (or at least seems like it) it can be difficult to grasp the issues at hand. Yet as a very busy person myself, I do get that there more then likely isn't enough time for you to sit down and play Blade and Soul as a 'normal player'. Even a full run though all dungeons in Cross Server/F8 can take a couple hours if the party is inexperienced or not well geared.
I think that's part of why some players hope you'll start doing update streams again like Hime used to...they want to see you experiencing the game. I personally would be thrilled if a NCSoft employee tried it from the perspective of a normal player. No GM access, no special clients...just the game as it is available to the rest of us. And that would grant even further context to the issues we bring up.
As for the regional differences, it is currently well known that there is virtually no difference between NA/EU and the RU clients except language and the timing for their anniversary event...but there are significant ones between those three and KR. Changes that do not make much sense and have never been explained to us. Why is it literally 60 times harder to get Starcross accessories and the Upsurge Weapon compared to KR, where they can just do Stage 1 of the relevant dungeons? Why are costs for upgrades set to KR values, but our income is less then a fourth of theirs? Why were gem boxes in Chaos Supply Chain reduced an entire tier in what they give? If these issues were explained and justified, that might dismiss a lot of the frustration, but as is, we need to work four times as hard to upgrade and sixty times as hard to clear content to get the base item for said upgrades.
