This makes no sense at all. You can't just take an idea and add something on to it without careful examinations. It'll become absolute crap!
Let's make 1 thing clear for you. Hermits are good at bossing because they just run away while throwing stars with dependency on critical hit for knock back. It's not something I consider to be fun, but let's just call it efficient.
Chief Bandits have knock back damage (lawl @ all bandits unable to knock back). However, using Assaulter on a Boss will usually result in taking damage due to the monster's size. So if you're going to take damage, you might as well use SavageBlow since it's faster (lawl no knock back).
A "sindit" is dead as of level 37 or whatever which is the end of the period a "sindit" suffers while training. From lvl 37 a "sindit" will cease to use stars because SavageBlow combined with DaggerMastery will do more damage than Lucky7. When people talk about bossing, they mean at least 3rd job (lvl70) and up to kill crap from Jr Balrog and up (because mushmom and Z mushmom are *** lolololololol).
and I'll repeat because this is the key point you missed, sins are good at bossing because they have knockback due to CriticalHit/ClawMastery(Assassin skills) and can just spam stars.
