It says you get 5 percent more probable to crit from elemental oath, after you crit.

Seems that .4 seconds off of 6 seconds is more dps ... well its umm 6.66 percent more dps on shock spells.

Ok assuming a crit is 100percnet more damage 5 percent probability is ummm 5 percent more dps, per player. For a group you get 25 percent more damage time the probaility you will get a crit and other will crit within 15 seconds ...

Well I guess its wise to get one EO per group then....
