The release of Legendary Armory was great, the ability to toggle trinket effects on and off as well. (Maybe we can have it for legendary armors too?)
How about we take it one step further and make legendaries scale with level like the Dreambound and Bloodbound Weapons do?
This has probably been brought up before but even if it have, I feel it's worth mentioning again.
I would also like to see some improvements to the Skyscale, it's slow at ascending which is not that big of an issue, but it's very slow at descending which makes no sense. Most of the times it's faster to just disengage and mount up a bit further down rather than to just descend normally. Draconis mons is a good example of where the skyscale test your patience.
And last but not least, as someone stated yesterday, please make it possible to merge the tomes.
Edit: Please make the Candy Corn Gobbler function like the Snowflake Gobbler so that we aren't forced to have the actual materials in our bags if they are in the material storage.
