K guys. I will be pretty busy IRL for the next month, so I wont be able to further test this until im back and got more time... Im just going to post the results i got until now. As it is kinda impossible to parse a successful FD i had to write all the infos down, and cant supply you with a "valid" parse. Here goes:
FD without a mob (no agro on anything)
1000 FDs, 24 Fails = 0.024 = 2.4 %
Thats pretty nice actually. In all this time I had 2 double Fails. Acceptable
FD with 1 mob agroed (used the mob on the right side in Lab, lightblue spider)
1000 FDs, 36 Fails = 0.036 = 3.6 %
I really have no clue why there was more fails. In all this time i only had 1 single double fail. The fail rate was 1.2 % higher than without a mob agroed.
In comparison to the 1st results without a mob agroed, there was a 50 % raise in fail rate from 24 to 36 fails. (notice: Raise in fail rate. The actual FD fail rate was just 1.1 % higher)
Overall, the results about the actual % of fails was rather a positive suprise for me.
Unfortunately i dont have the time for further testing right now, as i will use the actual time i have to play raiding instead of FDing over and over again. When i get back I will test with 2 mobs agroed, and then proceeed to the more than 2 mobs. You are all welcome to do the testing as well, especially for those that are just going to say: 1000 FDs is not enough. I agree that its a very small number for statistics. Go ahead and do your own testing, and post your results.
Something thats not offical but ive noticed in testing: There seems to be a chance for a fail, when there is a bit of PL. Kinda comparable to the "Fizzle on Lag" Phenomenon. But this, right now, is just speculation. Feel free to flame away, anyway
Have a nice summer
Lance
