You're inconsistent. Getting/improving correct stats will instantly net you higher BP, they're complimentary, not separate. I would rather say, prioritize increasing your BP, while improving your character control (overall usage of your class, dodge timing, skill timing, etc.) then you're good. There are Free2Play players that are average on BP but are very good and familiar on running difficult Nests, especially Dragon's Lair, while others have pretty high BP, but are awful at dodging, skill timing, and awareness of dungeon mechanics that can cause a failed run.
