Presence of Mind Buff.. ?

[OrganizationXIll]

I just don't see why this skill is on a 5 minute cool down. It isn't potent enough to warrant a 300 second cool down. It is a handy skill to pop off in a pinch or to shorten other cool downs. (Benediction) Does anyone have any stats for this skill? How much does it decrease cast and recast times? What kind of buffs do you think it needs if any? Shorter recast? Same recast but potency buff?

EDIT: I know what the skill does and its uses. I am just saying for 10 seconds of this fairly useful spell 5 minutes for a cool down isn't warranted.

EDIT2: It ends up being around .4 seconds off each cast. Typically, you get 4 casts in it and you end up saving 1.6 seconds every 5 minutes. So in 10 minutes you get ONE extra cast with this skill. That is pretty close to useless. However, that is not all. Ever notice that it generally takes a second for it to take effect? Yea. We throw that in there and its a whopping .6 seconds every 5 minutes. That brings us to 1 extra cast in about 25 minutes. So in my book it IS useless.

I am now abandoning my position on a simple cooldown recduction. After looking at the numbers, I feel it needs a raw buff to the potency of the extra speed or a much longer duration. Double one of the two and look and see if it becomes OP. (Doubt it) If it somehow does, just shorten it a little.
