I wouldn't say this necessarily sets a bad precedent. This would have to be new for a precedent to be set. Ultimately this company has been auctioning off legos under the guise of RNG for years now. If you spend enough you'll get the champ eventually. Even ignoring RNG anytime they did a guaranteed they were essentially selling the champ at a set value because you could buy the shards. The same can be said about fusions - just add up the value of
I'm guessing Xena is going to be pretty underwhelming, just like Wurlim was. I also doubt the pricing for this pass will mirror the original Battle Pass which I think was $25 iirc. Given that forge passes are $20, I'd guess this pricing comes in somewhere are $50. From that perspective it's actually a boon to the low spenders players because they've never sold a champ that cheap before. We'll see if that prediction holds true.
Personally I won't be thanking the whale for spending money to keep the game afloat. Plarium could just as easily reduce their pricing and open up their market to a lot of other customers, but they rely on dopamine addiction to compel irrational spending habits. I'm sure Doc Blur can confirm the science behind this. He should be thanking me for being the fodder for his $100k account. Personally I think there is a lot more enjoyment in being F2P or low spending and still competing with the whales.
I started playing Watcher of Realms recently and you get a lot more value spending there, and on top of that the developers really make an effort to listen to the playerbase and try to make the game experience better. I don't mind supporting the game when it feels like the company values it's customers. Plarium unfortunately has made me feel taken advantage of in nearly every interaction I've ever had with them. Case in point - there are sooooo many QoL features in WoR that were either present at launch or have been implemented quickly and effectively as a result of customer feedback.
Plarium acts quickly to address anything that impacts their bottom line but anything that impacts the players seems to take forever. See the Emic Trunkheart bug, or the continued insistence that Fortus is working as intended (after selling him via guaranteed). There was the Geomancer nerf fiasco post-guarantee as well, and it took them how long to fix Corpulent Cadaver? Now Trunda is doing the same thing albeit to a lesser degree but she's "working as intended". The list goes on and on.
Anyways, obviously everyone should make their own decision about whether it makes sense for them to spend more in game. While this new "feature" (really a product...god I hope this wasn't the "content" that Cirilla teased in her recent interview with Ash) doesn't really set a precedant, it could ultimately be damaging to the game. I worry about how this could escalate. Will they eventually be selling off Taras level champs at extremely inflated prices? That's not a game I want to play.
