Although I still disagree on the loss of essence (Burning Embers has the slow, just for instance, and let's be frank, we still have Wind-lore, Ancient Craft, Sticky Tar, Bane-flare, Blinding Flash, Sign of Power: See All Ends and Sign of Power: Command, and the Frost-lore, Fire-lore and Storm-lore are not that very difficult to get, especially not with the expansion that will come next year with even more points to spend) I do believe that in several ways the distribution of skills within the trait trees could be better. Your statement that we don't have debuffs though is in many ways not true, as, as can bee seen in my list, we still have 7 of our CC skills at our hand at any time, and the only ones affected by any changes are Wind-lore, whilst Ancient Craft and the stuns can be made more potent by traits.
Other than that, with our most important debuff skills, namely Fire-lore and Frost-lore, there have been incremental changes. Personally I'd like it more to see those two replaced by i.e. traits giving you Bane-flare in addition to Blinding Flash and Sign of Power: See All Ends in addition to SoP: Command, but this close to launch day I don't think that would happen soon and even I don't believe that to be a problem enough to have the release date be postponed for.
