This is the same situation with personal housing.
Before personal housing, Yoshi-P said personal housing will be much more affordable than FC housing. When it was released, it turned out to be a complete lie.
Before red scripts, Yoshi-P said red scripts are a way for the casuals to slowly accumulate gear and don't have to meld stuff, while the people who want to progress quickly can just craft their gear and overmeld it. When it was released, it turned out to be more more like the end-game for crafting/gathering with everyone gated behind red scripts.
The expectations they had players build up was that red scripts can be ignored by the "end-game crafter/gatherers" who will be doing the same as in 2.x: craft, overmeld, be done with it; while the casuals just have to slowly do the weekly cap and eventually will have the same level of gear as those overmelds. But in the end they force everyone into the red script grind, so they had to make it take longer than what the casual players expected.
Red script amount was never the problem. Red script itself forced on every gatherer/crafter is the problem. Once you let go of the end-game crafter/gatherers, you can design a red script system that involves little or no RNG, takes much less time (30 minutes a day for 6 days, like Ex.Roulette?) and not bound to timed nodes, i.e., real casual friendly system, for the casual players.
Put simply,Squre Enix is just saying, "okay I know you ordered steak and we gave you pizza, so I'll give you two colas instead of one, happy?"
- hardcore players are saying WTF because of the gating not because of the time required or the RNG;
- casual players are saying WTF because of the time required, the RNG, and the timed nodes, they don't mind the gating.
