One of the things I've missed over the last few years has been the stripping down and/or removal of most flavor text from things like exploration and slayer deeds (the thing you see when mousing over the completed entry on the right-hand side of the deed window). So it was wonderful to see that slayer deeds in the Vales give a (sometimes quite funny) quote from Radagast or someone else in the zone, and that each location in the various exploration deeds comes with a meaty, often multi-paragraph description. The little stories on the item tooltips for the Black Book quest rewards, which even differ in interesting ways depending between Might/Agility/Will gear, are also a nice touch.
I know this is a relatively minor thing which is easy to miss, and it makes me very happy that someone at SSG put in the effort to add these little lore rewards. I wanted to assure whoever's responsible that their efforts are noticed and appreciated, and that they brought a smile to my face. Keep it up!
