Hi
I've not played D&D in a looong time our group were hardcore AD&D 2nd Edition revised players who used to bath in its light for a minimum of 12 hours oft times moving into 24 hour sessions; fueled by coke, chips and coffee. Of course we were all unemployed bums back then

So enough about me.
I've just downloaded the latest playtest package and am in the process of creating a few characters, when I hit backgrounds and specialties. The process according to the guidelines is
Stats
Race
Class
Background
Specialty
Now after reading through the specialties I tend to view them as "Pathway" to a players "Background" which in turn gives reason to why the PC chose its "Class".
eg
Specialty - Healer
As a young Mountain Dwarf I found that I had a strong empathy towards the sick and injured, the local healer; whom I assisted, began to teach me the ways of healing through the use of local herbs. We found that I had a natural skill for healing and soon I surpassed my teacher, they then suggested I should perhaps think about becoming a priest and dedicating myself to a diety.
Background - Priest
With my teachers advise I entered into the "Divine order of Light's" service and as with my skills in Healing I found that I was very quick and;to my surprise, worked my way to the top of the order. After a few years my orders Head suggested that I should not waiste my talents here at the temple and that my skill would be of better use as a Cleric.
Class - Cleric
You get the idea by now

Of course for the specialty you may have tried the Healer but found that you weren't cut out for it and moved into a different background from there, but still retained the skills from the specialty.
So my order of character creation would be something like this
Race
Specialise - "Pathway"
Background
Class
Stats
My 2 cents... so far...
