It's really quite a simple three-part fix.
1) Get rid of this +bab bonus that monks get in game. monks are a 3/4 class and just raising their bab to emulate flurry is a lazy workarund.
Agreed
2) Add a glancing blow at full damage + weapon effects at levels 1 and 11, when unarmed, wielding 1 kama or a quarterstaff.
Do monk's have this in PnP? I do not remember seeing it.
3) Add a -2 penalty to hit when unarmed, wielding 1 kama or a quarterstaff.
How would this help DPS?
There, flurry properly implemented, unarmed, 1 kama and quarterstaff combat improved and more motivation to level as a pure monk.
Seriously, the code for this is already in game. Glancing blows are not a new thing, and the code for them to do full damage + weapon effects is in game already (they nerfed it, but it's there).
Adding weapon effects to glancing blows would overpower the effect and to add it to a single class's attacks would be unfair for all other classes.
Thoughts? Let's do it!
