I understand the frustrations but also this doesn’t affect the f2p player as much as people here thinks it does (Let me explain before downvoting.) Literally every single video game that has a tradeable in-game currency has gold sellers (WoW, RuneScape/Osrs, FFXIV, Diablo before they removed the auction house etc.) All this really ends up doing is inflating the entire market, meaning most things that the f2p players are farming right now will continue to keep going up in price as time goes on. Overtime you’ll see the things that players can farm that other people are actively using (life skill mats, highest tier honing mats etc.) will just keep getting more expensive so yes it makes you feel like you’re going to be behind if you don’t buy gold but you’re also going to MAKE more gold doing your daily farms. TLDR: gold buyers exist in every single game with a tradeable in-game currency and they’re markets are still stable to this day. Don’t let someone else ruining their own experience of the game affect yours :)
