100% agree with everything OP said. This attempted monetization of 6th job is disrespectful and outrageous. The playerbase will not stand for being treated like this. The game is more popular than it's been in over a decade, so stop trying to ruin one of the biggest and most hyped updates with your greed!
We're really asking for the bare minimum here Nexon: we just want to feel like you actually value and care about the GMS fanbase, but instead we're constantly made to feel like we're an unwanted stepchild compared to KMS. GMS is more popular right now than it's been in over a decade, so please don't ruin this good momentum with short sighted greed. Revert these horrible nerfs to Sol Erda, Oz rings boxes, the event shops, and most importantly stop trying to slip stuff like this into patches under the radar. It's frankly insulting to your playerbase to act like we're not even worthy of a proper announcement before you try to pull something like this on us.
