Elemental weakness or projectile weakness with LS

I run as marauder with lightning strike. 90% of mobs die to my projectiles, and not main hand attack. I also have a totem that spams curses for me. Question is what is the best curse for my setup? Elemental weakness or projectile weakness?

Ele weakness decreases their resistances by around 40%, while projectile weakness increases my proj. damage by 30% atm and adds 50% pierce.

Which one would make me mow down mobs faster?

I have no experience with this setup but from what I've read I would say elemental weakness, solely because if a mob gets the electrified status it will take more damage from the next elemental attack.

Projectile weakness would be an interesting choice sometimes, but I'd go with EW in most situations.

About 2/3 of the damage in each of my LS projectiles is elemental. I run a high %IPD staff. Against a 0-resist mob that means a 46% EW would give me .6*1.46 - .6 ~ 25% more damage.

This effect is way more pronounced on high-resist mobs. For instance, EW would actually improve my damage by more than 100% on 75% resist monsters. Bonus there, the really tough monsters are effected more by my curse than the ones that are already easy. BIG bonus.

Also, LS is a 4-component ability, and projectile weakness only affects the projectiles. There are plenty of situations you'll find yourself in where the projectiles might not even hit anything, so PW becomes kind of unwieldy.

HOWEVER, the pierce effect could be pretty strong on projectile weakness, especially if you're using proliferation.

Just my thoughts, someone else can probably come up with a strong case for projectile weakness.

I've been testing around abit with it now, and it seems to be quite a good choice actually compared to EW. Specially in tunneled areas, the pierce makes mowing down large groups pretty fast.

I am not totally convinced though. Another good thing is i am marauder with basically no extra int, so i can get me projectile weakness skill way higher than elemental weakness. But i am really not sure which gives me the highest boost to dps really.

Perhaps wait until they have damage numbers displayed.
