The situation is significantly less toxic than before.was? How is it not binary now? Heatwave is still there. This is poison all over again, instead of addressing the issue they throw in something else that doesn't address the root cause. They can't remove Heatwave because scenarios are too powerful so the game is now binary, you either have it and win or you don't and lose (unless your SK or NR for obvious reasons)...Every broken mechanic in the game at the moment was the devs own doing and on some level incompetence. They don't appear to be learning from any of their previous decisions.
That being said, I agree that Shupe should lose the artifact removal option (even if it is sh**), as well as heatwave losing the artifact removal capabilities, after that Scenarios have to be balanced around being unanswerable and the only way I see for that would be to redesign them with lower provision costs and lower ceilings, even if they spawn only 4-5p bronze cards, those are already insane enough as is, if you multiply their power by 3.
They could also make Scenarios immediately spawn their main plays and have an own engine capability (similar to the Mystic Echo replacement, having Symbiosis) with 1-2, maybe always 2 points if you do what currently triggers their chapters.
The flaw is that Scenarios right now are super low initial tempo, so they give them a large potential, that design is on its own already flawed by necessitating a high ceiling.
Siege: 11 (12?) provisions
Deploy: Spawn a Reinforced Trebuchet and a Reinforced Ballista in your Ranged Row, then damage them by 1
Chapter 1: Give 1 charge to a random Siege Engine that a charge can be given to
Chapter 2: Inflict 1 damage to a random enemy unit
Trigger Chapter 1 every time you play a Siege Engine
Trigger Chapter 2 every time you play a Siege Engine, unless Chapter 1 was triggered the first time
I.e. Chapter 1 will always trigger, while Chapter 2 will trigger from the second Siege Engine onwards.
This way Siege would incentivize to play more Siege Engines and scales up with them, while still not easily giving the value of 3 bronze cards, yet not being all too slow.
In this case I would say that this would reflect the Scenario of a Siege much better than the Scenario does now.
