How bad are the rip off dark summons!!

I had some itunes vouchers and invested £30 of them on SP for dark summons and during the entirety of the dark summons i received Just the 1 trashy A.
Other people had this? Just a complete rip off. Rest of the time i've mostly had non ability b's
Barely had anything in the invite summon either, there just taking the piss with it!!
Screw these people

You certainly would have done better investing in energy potions and trading for what you want. Some trashy A's will sell for only a few EPS.

Only spend money in events,

In the event of the tower, x10 x100 my energy potions and at least one A guaranted (bayard, asura or lewd)

In the event of the spirits, x100 my elixir with one darksummon.

As you can see, you get more when event runs.
