If you weren't already aware, (unranked) Condensed White Potions can be purchased directly from Thanks Ticket Machine (/navi prt_gld 165/50) for 4,666z each (14 tickets for 30 potions)
I don't want to purchase 30 at a time!
You can purchase 1,500 at a time.
The ranking bonus makes the difference between surviving and not!
As far as PVM is concerned, in what situation? I can only think of Bio3/4/5 MVPs, but using ranked potions won't help you there if you aren't a Sura, and if you are a Sura then unranked slims work just fine.
