See? As I said, you don't understand how it works.
Pride weapons give a you Assault which is always active. PLUS Pride bonus as your HP lowers. Since all content which isn't a joke for you WILL hurt you, Pride weapons are good. It's not a question until you have a full SSR grid - Prides belong in your grid. And by the time your grids are full of SSRs, FLBs will be out (very, very soon now) which means that Prides still belong in your grid - NO FUCKING QUESTION - until you have a full grid of FLBs. We're talking about 15% base Assault, plus Pride effect and a secondary effect.
Pride weapons are good. Really good. Think of them as "good weapons with a bonus effect as HP drops."
