I'd have to disagree. Even with zero poison resist, if you factor in the cast time and hit percentages my calculations come up with a negative overall dps as compared to just autos.This is completely incorrect regarding life steal, back before tower update I could hit 1.5-2k life steals on normal mobs and on mord/snorri due to no poison resistDon't use ls if you want max dps, because it's ALWAYS negative dps no matter how much dex you have. Go with somewhat balanced str/dex (3:2 either way) and use ss qs rip sneaky pw, in order of priority if you're not using hastes, and ss qs rip pw sneaky if on hastes.
Done deal.
In extreme cases, LS can make a positive effect on dps, say, when the following apply:
• you have 1450 dex, lvl50 ls
• ls hits 70% of the time (not sure if this is realistic)
• you hit 70% if your autos, and your auto page damage is ~1800
• you are not hasted (just the 30% haste from ring or offhand)
And by then, your LS can make 8,727 extra damage in 15mins (compared to if you use the cast times to just auto). Compare this to 131,978 extra damage for ss @33% hit chance (!), or 58,261 for Sneaky @50% damage resist.
But then, your other skills will suffer.
So if you want a fast levelling build, and especially if you have a healer buffing and healing outside of group, ditch ls.
