I found this subject being discussed within the Japanese conjurer forum and I thought that a panel here in English would be appropriate as well. As the title of this thread suggests, the subject is on the duration of the spells Protect and Shell.

I, too, believe that 5:00 minutes is an insufficient amount of time for these spells to last. The ability Roaming Soul allows the effects to extend to 7:30, but it is still too short.

While these spells are manageable during solo play, a frequently mobile party roaming the battlefield completing levequests or fighting notorious monsters would require many breaks in order for a conjurer to keep the effect on the team and him or herself. With a 1:00 minute recast time, it is important that Protect and Shell is distributed to the entire team all at once, lest either the close-range or long-range players miss out on some crucial protection.

I can foresee adjustments in the following manner:
- Increasing the effect duration of Protect and Shell
- Lowering the recast time of Protect and Shell
- Progressively raising the effect duration of higher tier Protect and Shell spells as they are included
- Increasing the amount of time extended to spells cast with the ability Roaming Soul in effect
