If quests gave SP for rewards I'd kinda hope they come in pages like in XI, and random at that. ):
Battling is the core of the game, to quest grind for SP is kinda counter productive especially since we're waiting over a month and a half (And maybe since release) for this upcoming patch?

Oh but you mean by killing the mobs related to the quests? Then yes. :> XI in its prime offered great rewards, after the battle fixes are in place we can probably start looking forward to better rewards than ones based on the handful of recipes we currently have.
