Some random calculations just thought I'd show you with max optimization and stats for Sothe & Heather... (Heather doesn't get a +10 crit, dodge bond though). (Best biorhythm btw.)
Volke with innate +25% Crit, Lethality, 35 Str, and 40 Skl cap he screws them both in the arse in terms of effectiveness and awesomeness. (I think he might have a Bastian +10 transfer bond though... not sure)
As for whispers in general they get a +10 luk cap over assassins woo! haha.
Basically comes down to assassins's doing quite a bit more consistent damage, criting more of the time by far, and slightly higher skill activation while trading off for lower crit dodge, lower avoid, and SLIGHTLY lower accuracy.
