I also use TG legs in mine, if you can fit either or both the TG legs/arms I would recommend it. I see a lot of people using Tuscar's bow, presumably for the higher delve dd proc with the 3% increased chance of procing, but I prefer using MP dot/lt proc bows. As fas as spears, you're better off using 3.9 speed thrust lt rog and a 4.3 speed slash lt rog. What I do is start the fight with bloodfire until the dot procs then switch to either one of those depending on my target's armor weaknesses. Throw a dex/qui debuff on a crafted 1h sword and a dd proc on a player crafted shield for rupts. Grab a Noxious Fengundar Pendant (I have no idea if it's a feather item tbh mine was given to me) for a useable melee health buffer. Legion heart of course and you're good to go.
