Every new character that is released alongside a new weekly boss always requires their materials but we only get 1 chance to fight that boss per week and the character requires a total of 18 boss materials for all 3 talents upto level 10. Even for 2 talents at lvl 10, we still need a total of 12 weekly boss mats.

Not even the first-boss clear rewards that they've added helps because we need atleast 8-12 and getting them over the course of weeks is annoying.

Not to mention the rare dream solvents drop, we get like 1 per 3 or more drops and we have a lot of characters to build so please if possible, either make dream solvent permanent per weekly boss fight or allow more chances to get rewards from each weekly boss.
Can the devs please remove the 1/1 weekly boss limit?
