So you mean to say this tables are abstract beings and note stored anyware (like any data files that exists). Seriously delisional, I'm speaking truth here. This *tables* can be pulled and downloaded by any agent with access to the backend portal, there is no mysticism, hate to burst a bubble here but all the flashy good looking things inside a game is all data - numbers on a table, proxy, database call it whatever you like, it is a code attached to an Entitlement ID or Template ID which is then stored somewhere this is how your progress is saved in game, even if you have experience on a private BNS server it doesn't mean you had access to this internal portal.
And, my apologies I have not worked for a game company, I *work* and I know how easy it is. This portals cannot be access by anyone, only by people sharing the same IP address from a given network + 2FA code sent to the company's email address. So working on a private server is redundant to an actual tool creation or inside process.
It is irrelevant whether other publishers do it or not? This is just cattle mind, I'm unable to see how something like this will not benefit both parties and why you wouldn't want it.
Gaming companies, are working daily on evolving their tool and processes in order to improve their player experience *seriously you have no idea how many back end updates they must receive each day*, for any upcoming event, update, balance change, bug reports. The best games in the market have opted for this ever growing game method because it works. I could list many examples but it is redundant. Even Guild Wars 2 which is under the same publisher *NCSoft* has a drop down menu which enables you to jump to different regions . Any change that could bring benefit to the players and company shouldn't be rejected.
