Of the melee i would like to note that Nin can in rapid succession cast katon twice then cast fuma, katon, and doton at double potency all the while spamming death blossom and eventually top it off with a hellfrog all within the normal time it takes for a full opener.
Potency wise for just the aoe moves thats 250, 250, 500, 80 dot over 24 seconds, and 400. all the while spamming blossom at 110. At a much faster rate than Sam and with no damage falloff for extra adds.

During a roughly 7 mob pull i was parsing just over 10k after 30 seconds...
