Roots and zoning/logging

[Tecmos Deception]

Was it a classic mechanic for roots (and snares) to last their normal durations even when the caster had logged out or zoned? I can't remember if using roots/snares to keep mobs at zonelines as a splitting tactic was something from classic or just from early blue or what.

On green currently, for sure, roots TEND to break early if the caster zones or logs (actually I guess I've only been logging, not zoning, so I'm not sure if there is a difference there), even when the mobs are greens and MR debuffed.
