I main orochi, when I face lawbringers it usually tends to be an easy-ish fight for me. You need to drain their stamina with your push after block and be extremely unpredictable, usually when I fight law bringers they don't put enough pressure on me and that just allows me to freely poke at them.
Also don't dash into the stam drain push, they can easily side dash attack it. Also the leg pull to chuck over head thing you shouldn't use at all against them unless they're out of stam, easy to dodge attack and even if you do get them with it you only get a single light attack. it's high risk low reward.
decent players will usually feint a heavy into guard break, zone or top light combo, just don't try parrying their heavy as it's most likely a feint and react to what they do next.
Also your unblockable has awkward timing on it so they'll most likely try to side dodge attack, take advantage of this by feinting ur unblockable and parrying their side attack!
Lastly, try to guard break them as much as possible, I always find myself watching out for that push or top light and a guard break usually surprises me
feint heavy -> guard break -> heavy -> stam drain push -> light
hard but possible!
Lawbringer is garbage, I'm sorry I wasted the time trying to figure out how to make him half decent but it's just not there. Garbage initiators, horrible combos, incredibly telegraphed. Any initiate into a combo lawmaker tries to make can be countered by literally rolling away. Only thing hes good for is spear pushing people off of ledges and shoulder flipping people while theyre in revenge.
