Trials of Osiris Lighthouse trip with Adept Gun should be points based & Flawless has additional drops.
Here me out.
Keep the "Flawless" rewards for getting 7 wins without losing (mercy included). (adept gun, ship, ghost, memento, emblem, ect)
Add a separate system to track points. "Triumphant".
Triumphant equals 21 points.
Wins while on a flawless card are worth 3 points.
Wins while on a flawed card are worth 2 points.
Losses are worth 1 point.
Once you reach 21 points you go to the lighthouse.
If you are on a flawless card you get flawless rewards and "Triumphant" 21 points rewards.
The triumphant 21 points reward is one adept gun.
In this system those that reach the lighthouse will get the normal flawless rewards and an additional adept gun.
Those that reach the lighthouse on a flawed card will get one adept gun.
This system incentives everyone to play to 21 points.
It still rewards those who can go flawless while give them an incentive to stop card resetting.
It creates a way for anyone to get an adept roll while rewarding them for just participating.
This would go well with the new FBMM system they have planned.
