While the "right" people are subjective from person to person, I feel some updates most people could agree with would be:
1) Salvage Update. ("Chest" at the beginning, etc, made it generally a bit more bearable)
2) Ullikummi
3) Sky gods dropping more than 1 pop item
4) abjurations from other sources (einherjar)
5) Lowered requirement for Alexandrite (even though they didnt lower it a lot)
6) Increased Iceland Drop rates.
7) Improvements to Treasure Hunter
8) Multiple Spawns for Monster in Abyssea
9) Splitting of BP timers to BP:Rage and BP:ward
10) Skilling up from Bloodpacts
11) Last Resort duration increased
12) BP:Ward range increased
13) Sentinel update from being just Defense to a PDT
14) Addition of Blink/Stoneskin to SCH sub.
I can't think of any more right now

but give them some credit... They listen to the right people sometimes.
