Precisely. In other MMORPGs this can be achieved even through the use of special poisons in the cases of Rogues, Assassins and such.
I wouldn't mind one that depletes target's stamina rapidly.

Normal warriors just have something like "Hamstring" as they often call it.

As for mages, I also agree to be honest. Something akin to that Spellweave spell only with an extra effect of slowing down the target. Cold Damage to be sure.

Yea, that effect would be better as a target-a-person rather than an area.

Though an area-effect spell would be fun for a large scale battle, but probably a bit over-powered
