I’ll chime in here. There is a certain psychological resistance to recycling excess 4* heroes. They’re rare enough that consolidating them for XP bumps to a sole survivor seems wasteful because there are ways of spending common resources to get the same reward. It takes longer, but since we’re talking about “spares”, the game doesn’t really offer any incentive for the impatience required to make acceleration a compelling value add.
On the other hand, that band of 4* heroes eventually starts to become a heavy albatross. When a player reluctantly recycles some lesser or more overstocked 4*’s to clean space, that’s a liquidation sale. Liquidation sales aren’t deemed successful because they generated profit, they’re judged by how well they minimize unavoidable losses.
If Monty Hall was hosting EnP, every trade involving a 4* hero has the upside of an old reliable toaster oven. There’s no gamble involved when the outcomes are predictable.
Animation Throwdown made a change to its card recycling mechanics a while back. There had always been a game currency, stones, that player could collect and then exchange for new card pulls from the random oracle, much like EnP’s Atlantis/Midgard/Legends coins work. The change hey made to recycling was a kickback in terms of a modest number of random draw currency. Nowhere near enough to come close to 1:1 replacement, but interestingly enough, the currency returned applied to higher rarity cards. One epic trades in for 1% of a random Legendary pull.
Timelines has a feature where you can bind up your characters for an extended time, netting a progressively large prize pool, but if you don”t pull them back in time, you risk losing it all. Same mechanic that made Deal or No Deal catchy.
I wonder if a higher stakes version of today’s tournaments could happen. Like playing for Ante where each round you might either lose your team or increase your price incentive for staying in. Survivors may opt out after any round, but opting out means forfeiting some or all of your accumulated prize pool. Limit all entries to un-ascended, level 1 characters of a fixed star rating to both even the playing field and put an upper bound. In the assets participants might lose for having entered,
Or, for a simpler route, how about Implementing a partial kickback for second chance Season 2/3 and/or seasonal pulls? Let probability odds favor then house, but not so much that somewhere between 5% and 10% of all participants are predicted to feel they wound up getting back something better than what they traded in,
