I think if he takes anything from Skyrim into FFXIV I would like it to be the fluidity of the storytelling. Imagine quests taking you from the main story to looking for some ancient crystal, to looking for a legendary weapon, to fighting off a dragon, all so seamlessly that it all feels like a single quest.
That and probably the thought process on leveling.
Early levels=easy to medium difficulty to obtain but little reward
Later levels = hard to obtain but great reward
That plus knowing this games love for references I fully expect some NPC to comment on arrows... and their knees.
