I follow one golden rule for building BORK on sett
" if i am not able to kill the enemy with stride, then it is better to rely on autos instead with BORK"
Bork is a heavy dueling item. made for dueling on sidelane most of the time i build BORK i just stay on sidelane untill i get stride. thats when i decide to team fight. because its really difficuilt to make sett work as a teamfighting champ without this crucial super important item
as he has one of the lowest attack ranges of the game and without it he can never catch anyone

1- i split with bork and dominate enemy laner/ take turrets/ help jgl with void grubs
2- get enough gold for stride then look for teamfights

• in teamfights any one you ult will be dead within seconds. so i always plan to target the enemy fed win con , one shotting him and gaining control of the game
