JotC can get up to 214 spell damage with the talent, libram, and pvp gloves. Which gives about 10 dps without factoring crits and nightfall just from the seal procs. Add in the judgement and it jumps up to 25. After about 16 seconds it becomes better than just judging command using those 2 factors. About 11 seconds if you add in consecration. So if you use it in the situations that it would do some good, ie. fights longer than 15 seconds, it is the best damage judgement.
