I have very fond memories of the attunement quests under the pre-merge worlds so I'm not opposed to attunement to all the new player communities that were added with the shard merge.
I did wonder at the time why those didn't require attunement.
I will agree that I think the attunement to the racial cities could have been skipped, but there probably is some design reason and logical progression from leveling that directs you from one racial city to another, once you hit certain levels.
In this matter, I can say I would support the suggestion of some grandfathering of characters with ratings/level in any class to be auto-attuned to those RACIAL cities or just not require attunement to any racial city.
