The pet is still worth using even though it only is up for 30 sec. specialy in a pvp fight or duel. I mean it is worthless in a pve fight only time I use it is for those big epic mobs to help on dps other then that it is not worth the waste of castign and using an essence anymore. If they atleast change it to where pet stays up for the duration of the encounter or fight then it would be worth it.
