HW 3.x part isn't long tho, it's 44 quests (ARR 2.x is 100 quests in comparison, and SB 4.x is 40). Even 2.x isn't that long. Just when you make all of these quests in one step it's... as if you came to the restaurant and they served to you the complete set of dishes at once instead of serving it partly, I suppose.

On the other hand, if you are attentive, you will actually notice that after every update people complain "why story patches are so short!?" (well guys... because you begged to not repeat ARR situation?) I bet that if they will do a golden middle for ShB 5.x (let's say 70 quests) to make story patches a little bit longer there will be whining in 6.0 "why so loooong" again. Fail&fail situation in any case. /shrugs

Anyway, they stated that they do some adjustments on ARR story as far as I remember so I would wait until they release it. HW and SB do not need adjustments, they are already short enough.
