Well.


I find that against dumb opponents, it doesn't really matter. NS EM will kill one target, then you will have to work on the remaining 4.. with TOWs you will have a constantly high killing capacity.. but anyway.. where it matters is against smart opponents that see the NS EM coming.

Countless times have I been completely spell reflected on my NS EM.. and rogues with a brain will see it coming from a mile away and do COS. That is why I currently prefer TOWs - it makes me constantly very dangerous. Often I can just keep nuking and surprise the healer with a CL+Shock.
