I noticed that the quest to upgrade 1 piece of your fortification (7 day cooldown) did not renew itself this week.  I liked that quest as it paid *part* of the emerald cost in offensive dragons as a bonus for upgrading your stronghold.

I also noticed a new *upgrade your fortification 21 times* quest that paid out def dragons.  

If this change was deliberate, it should have been in some patch notes.  Not that there are ever patch notes...

Personally I liked the old way better.  The new way gives you choice in what to upgrade, but I would rather have had a choice in the type of reward (off or def) as well.
