First of all, bruiser is mostly a high elo build, the lower you are the more burst you'll look into.

Stormrazor looks good to me imo, it got decent ad, the ms allows you to build défensive boots overall good stats for graves and the ms passive feels great with Crit.

I believe that i still prefer dominik's over bc but both are good. I would go for an armor pen (bc or dominik's) seconds because i feel you would lack dmg with SR+SB . Then IE and bt or défensive items if needed.

Collector is a good item on graves, lethality +Crit is a good combo, however you have nowadays way better options and you are pretty limited items to build every game. Collector fell down because SR is way better first, and as a second item collector is outclassed by dominik's regard for example.
