I finally gave the BoB duelling arenas a go last night - I'd totally forgotten they exist. The bridge arena is by far the best: no hiding, no spots to run to and estus, just pure 1v1 fightin' (also, 10 Force miracles with a fast cast means knocking opponents off the edge for easy wins: it never gets old. Force and Emit Force are vastly underrated in PvP - Emit Force hits for around 500, seems to have splash damage and it moves very quickly - good to change up with).
The other arenas are not nearly as interesting, I don't think. I wish the 3 statues referred to the arenas, and not just queues, but oh well.
Still in NG, at SL130/SM4.5mil (have double my SM from PvP and mucking around building up different weapons - also farming vessels adds up). Dragon Shrine is a bit quieter at this level, also running into more and more powerful opponents, who have obviously dumped more souls into their SL than me. Nonetheless, it remains a bunch of fun when lag permits.
Here's to continued hoping that SL becomes the determining factor for PvP matchups in the future. At SL150 and above, you can build characters who can have their cake and eat it too, whereas at SL125, a few more compromises must be made, which I really enjoy (hence the dozen or so respecs, the inventory full of +5/+10 items, Dragon Aerie bonfire at 14, Exile Holding Cells bonfire at like, 10 or something, and so on!)
Currently using a more balanced build, with focus on lightning and miracles. Wielding a +10 lightning Black Knight Halberd (the backstep 2HD light attack is devastating, no one picks it - it's a stamina draining whirlwind attack with three (3!!) successive attacks), a +5 lightning Chaos Blade as backup, along with the ever reliable +10 dagger for riposte/backstabs. +10 Lightning Protective Chime, which is underrated (140 cast speed, 253 lightning damage plus B/C FTH/INT scaling, makes it very powerful for lower-than 50 FTH builds). Good times.
