Why is Summoner the most ignored, misunderstood and broken job?

[Karbuncle]

1) Magian staff. As far as I know, I'm the only one who finished -pdt.

I have one (Well, Its almost finished...!)

2) Augmented hat, which I had to toss/rebuild

I got this for my BST/PUP :|, Considered it for SMN too, Sucks having mutliple jobs.
.

3) -mdt belt, I camped it for weeks based on bad information. My bad.

Selemnus Belt? I tried camping that, Evil NM.
.

5) 2 -10% pdt Atma, pre-Heroes.

Atma of the Heavens and? Can't think of the other off the top of my head.
