(This is not a fix my dps, i know i sucked at this attempt^^)
i checked the log from yesterday and was a bit shocked when i saw the immolate uptime on targets.
(we don't kill blue)
if i check the immolate mark for "buffs cast" it loooks like i had 7x immolate on blue, but only 3x green and 1x red
pretty interresting how that would be possible,
since i am hitcapped and only cast havoc on the frozen head, then immolate on the target head.
checking the uptime 346.7 seconds with a total of 292 ticks
about 15% haste infight so every 2.6 seconds a tick ...346.7/2.6= 133 ticks + haste procs a bit more
then i looked at the damage i did on teh frozen head and surprise 146 Immolate ticks there (146x2=292 total)
so i had immolate 100% of its uptime on 2 targets, but the display in WOL is wrong (sometimes)
Keep this bug in mind when heping someone to fix his dps
Edit: forgot the Wol link^^
