"We have made some changes on the Test Server to reduce melee class downtime. Regeneration should be faster while sitting and this should allow melee types to get back into the fray much quicker. Help us test this new feature and send us your feedback by using the Dev Corner feedback feature or by posting on the Official EverQuest Forums at eqforums.station.sony.com under On Test."
Also read in that thread they have changed it so one can bind to 70% (without aa) and also bind while sitting.
Interesting.
