Agreed, even if it´s only one level those are good news, plenty of cool abilites at level 11, like the improved divine smite for Pallys, fighter´s 3rd extra attack, monk´s 2nd monastic tradition ability (including the "sharpen the blade" for kenseis or extra element for element monk), rogue´s reliable talent or relentless rage for barbs.
...and the level 6 spells for full casters and warlocks. good stuff
