I believe this has been mentioned before but quest rewards stating local increase in quality of X currently (afaik) increases quality in a radius around the questgiver.
I suggest moving these quality increases to the realm instead, which also removes the quest giver dies - quality rewards lost issue.
In addition (up to debate), it'd be cool to see how much quest rewards have contributed to the realm by checking the thingwall, or alternatively you can see how much you personally have contributed (or both)
This would make players feel more part of a realm, and make quests (and in particular Q increases) feel more useful
