It's a bit bittersweet now that I'm more or less at the end of the content.

I'm kind of left wondering what the hell in going to do once I'm done. I'm not really into Souls and everything else I've played just makes me wish I was playing BB.
GG FROM SOFTWARE!
In my eyes you have three perfectly valid options:
1) Start a new character focusing on a different build / weapons (again, recommended ones are STR+SKL, BLT+SKL or ARC+STR).
2) Play Dark Souls, IMHO the only game that even compares to Bloodborne (skip DS2 though, while DS1 is universally loved DS2 is very divisive, I for one hate it and will leave it at that). Dark Souls is pretty much like Bloodborne, equally smart, with a bigger and more varied world (dark fantasy instead of gothic/cosmic horror, although it still as monstrosities like the Gaping Dragon), more emphasis on shields and no transforming weapons. The DLC is also great. Honestly it's worth it if only for the scholar/gaming history value of it.
3) Play Demon Souls if you have a PS3, although it's been rumored that a PS4 or PC port is planned so you might want to wait for that instead.
I think I wanma start a Bloodtinge build with the Chikage and Repeating Pistol. Tips? Earliest to get the weapons? Should I just run through areas until Cainhurst? What to do?
What I did was to pump DEX/VIT/END and use the cane until I got the Chikage. Worked well enough.
The biggest roadblock will probably be Logarius, but he's very vulnerable to viscerals and with a high DEX you'll do lots of damage.
