Super Bendandcough to the rescue, however i do not think rppm have a timer placed on it since the second u put it on your weapon. If that was the case ppl could just stop dps'ing for a certain time then dps for the last 5-10 seconds of their minute and get superb burst from ef. I always thought it worked like this, You place a dot on a target which lasts 15 seconds. If you have 0 haste then it is 10 ppm, that dot takes 1/4 of a minute, so on average you should get 2-3 procs for that dot. Of course if u place a second individual dot on the target that too can get ef procs. Which is why its effective for dot spreading or classes that have alot of spells up at once.
