Oh, I've never doubted the soloing part or -pdt in general, just that it's a nice luxury to have in those situations, solo or pt wise and worth getting once you've completed your tp and ws sets.
Though all the best main pieces (head, body, arms, etc) are hard to get :(
Accessories, aren't too hard though if you have the time and some gil (Dark Ring farming, Mollusca mantle for 2.5 mil, etc).
