Some of the gating is...okay.

The main thing I'd like to see done away with is so many things having "allowances"

Why can we only do 12 beast tribe quests a day?
Why can we only do 6 custom deliveries?
Why are leves capped at 99 and refill so slowly?

It didn't make sense in 1.0 and I'll never understand why they kept some of these things in ARR.
