That comment about assassins, I guess I meant before they messed it up with updates.
Moebius Strike / Death Blossom has been around for quite some time though. Hit & run in PvE is inefficient anyway.
Well... I'd like to put it as such that assassins (as they are) are not really made for GW.
They would be much cooler (in PvE) if killing a single enemy would actually matter compared to simply c-spacing and spreading AoE as much as possible (which, as a total aside, dervishes are basically made to do).
Indeed that is true.
It's also ironic that assassins are famous in PvE as solo farmers, which is the most un-assassiny thing I can imagine.
If you use pious haste you'll strip vow of silence, and then you can immediately reapply it. Do it fast enough and no spells can hit you. Dervish also has some good skills to keep physicals from hitting them, although sadly its anti-kd is pathetic.
