Judging by the extensive testing you've done, I'm not really buying the "no WoW account" listed in your profile. Please fix it ASAP.
Since the Wotlktalentpatch came out i was missing the Addon Sorren's Easy Rotations. It was never updated und became useless cause of the autoshot unlink. Since 3.08 when was starting playing survival i start to remember this great mod.
Bad Rotation (Aimed before ES and SS before refreshing Serpent)
I have no idea how to program in lua and i dont want to learn it. I made many compromises in doing this. I hardcoded the lnl proccs simply by setting the cooldown to 2s instead of watching the debuffs of the mobs. Same with Serpent Sting. I compared the result with classtimer, powaura und ghostpulse. It works fine so far but its dirty programed.
So, why i post this here? I hope that some more talentet programer seeing this and maybe update this really great addon for the community. I dont think it is so much work.
Thanks and bye.
