Ok I will suggest 3 reasonable adjustments which I think could make this better without removing the system they have designed.

(1) Reduce the cost of certain red scrip items so that people can do more with their weekly allowance, reducing the feeling of being gated so much.
(2) Increase the amount of red scrips earned from submitting collectables, so there is less repetition and less time required to meet the double weekly caps.
(3) Introduce alternative ways to acquire some items, in particular crafting materials, such as new Gnath/Vanu tribe quests or tomestones of law purchase.
