EDIT: the BS rule is a little confusing. I started out doing an occasional BS, like one every 2 or 3 fights. But, even then, I had people complaining.
What I'd like to start to do is this
1. Occasional BS - especially if they leave themselves open.
2. Mainly roll BS (but if a pivot BS is wide open, I'll take it).
3. No strafing to fish for a pivot BS.
4. No more than 1 BS per fight.
5. No Hornet's Ring.
Does that sound fair?
Sorry to be a pain about this, but I find BS to be a good part of the game - especially if they aren't spammed. It gets my adrenaline pumping just knowing I may be BSed.
