For my example I'll use Shroud of the Avatar.
When you purchase an expensive enough pledge or bundle for SotA you gain access to an area in the forums called Dev+. This paywall access forum is supposed to give you a more personal dialog with game developers and allow you access to test servers prior to changes going live. There's always been friction in the community concerning Dev+ access and the potential for finding exploits and using them for economic advantages mostly because SotA is such a RMT heavy grind.
But now it seems that the developers are giving trade information to folks with Dev+ access, and people are pissed.
Obsidian chips are used to create rare Obsidian weapons... these weapons are then used to farm Cabalists and Obsidian golems which give Obsidian chips and also drop valuable artifacts and rares... that in turn command extremely high RMT prices in the forum marketplace.
Currently in the live server, 1 Obsidian ingot can be forged from 100 obsidian chips, and that's how it's always been since SotA went live a year ago. Now the devs are telling Dev+ backers that in the next live release Obsidian ingots will require 1000 Obsidian chips per. Is this practice fair to the gamers that don't have Dev+ access? Whales are buying access to Dev+ and cahing in on every release, and now they're buying up obs chips and weps like it's nobody's business and there's a heated debate about the integrity of the developers and the viability of Dev+.
Now I'm curious to know if other games and developers put insider trading information behind paywalls.
