If only you could get kenkonken on test /sigh.
The ability is a waste, at 5 minutes or 10 minutes its not really needed.
Here is my data on it:
+2 body/buffoon collar +1/af gloves
(blm head/frame)
activate
wait 0 seconds
ice maneuver every 10 seconds (no macros just full timing those 3 pieces)
average 8-12 ice maneuvers before overload
same as above:
activate
wait 2 minutes
12-15 ice before overload
conclusion:
if your nuking you at most can do 2 nukes before you need to DAD
1 cycle is 3 x ice + time to nuke = 45 seconds avg
2 cycles i 6 x ice + time to nuke = 1 min 30 sec
Even with 2, you run 0 risk of overload with said gear
So you will never need to use it....
NEVER
Now if you have MM atma up and are letting your pet stay out and chain nuking with 3x ice it would be on your third before you can overload, and at which point your at close to 3 minutes. Thing is if you have atma/mm you have crour buffs and thus should make it through the third cycle... at which point your going to be casting aspir anyways.
The only other viable set is ranger with 3x wind. With barrage/AS however your going to be ridding DEA since its gonna be dieing so often ;-p and then overload doesnt matter either.
So again, when is this ability needed?
