3 Questions Pets/Ench/Duo

1) You have to time them yourself, or eyeball it (if it's a haste buff, see how fast the pet is attacking, etc.).

2) Most buffs scale in their duration with level, and I believe quickness is no exception. You can do a /who all enc 20 30 (or whatever level is relevant) and ask those enchanters how long their quickness lasts, and compare it to a higher-level enchanter. Chances are, the lower-level ones will have a shorter quickness.
