Slow is huge agro. Lifetap seems to be same agro as DD (i.e. proportional to damage done so the 80hp tap on blood point isn't that big.) Stun is solid (equiv to 400-ish dd/tap), which is why ykesha stun+dd (threat of stun+dd counts both effects) can be effective even tho the melee threat from the weapons is poor.

Debuffs (like Frostbringer proc) and Dots (like Trochilic's Skean proc) are v good agro. IME Trochilic's Skean was noticeably better agro than Blood Point despite inferior ratio (unless it refused to proc, ofc.) Snare should be better agro than it is here (i think), but does not seem to get any threat at all when the mob already has a snare on it that your proc snare cannot overwrite, so snare whip is limited in value as a proc weap despite its nice off-hand ratio.

These values are from memory on live, so might not be 100% accurate:
mainhand agro = (dmg*2)+level_bonus per swing
offhand agro = (dmg*2) per swing (remember swings only on dual wield and has less double attack swing chance)
2h weapon agro = ((dmg*2)+level_bonus)*0.70
dd (incl. lifetap) = max damage (i think, might be damage done instead)
slow ~ 500
stun/debuff/poisondot ~ 400 (i.e. any stun, druid/ranger/chanter debuff+dot spells, & necro/shaman poison dots)

If you rely on proc weapons for agro (i.e. if you are a warrior and you don't hang with casters who worship at the altar of root) you will have some trouble holding agro vs. lazy monks and rogues and rangers. p99 is home to a lot of DPS melees who can't be bothered to actually use their threat reduction abilities, some are quite obstinate in their refusal but we can educate the rest.
