ok, ROGUE, my bad.
But, my point was that depending upon your view of street fighting, a ranger would do it for you.
don't get me wrong, your vision can include uncanny dodge and sneak attack.
Basically, I was (trying to) do two things. First bolster the idea that the core rules allows for the character type he described, second, describe one way to do it with a class that had not been mentioned but one time at that point in the thread.
...
now on to the rest, yes, there are some character concepts that don't fit, but I think not many (ok, change that to many less than the 2e days) given the multiclass rules.
as it stands, the original idea of trading the armor prof for others suggested feats is just bad, imho.
now, i can see cases where trading one feat for a different one might be fair and equitable.
g!
