Here i'll just start a collection of things that should have a reduction of timers now that the overall pacing of the game is much faster when compared to the older FFXI.
My first entry: The Signal Pearl.
Even without questing this thing sits at a pretty 20 hours. When he/she is present and fighting, the cap is about 15 mobs. Given the present state of the game, I would settle for a 8-10 recharge, given the fact that you can quest and get that reduced.
Any additions to the list?
