Guild Wars 2

So for longer fights I came up with a slightly improved rotation for D/D thieves. The general concept is your using the initiative you gain from Infusion of shadow (instead of taking Flanking Strikes) to replace Lotus Strike (7866dps) with a Heartseeker. (8977, 13467dps)

Old Rotation 6/6/0/0/2 (Flanking Strikes)
The current D/D Rotation

New Rotation 6/6/2/0/0 (Infusion of Shadow)
(Boss health 50%+)
(Boss health 25%-%50%)

(Not this method ALSO makes Infusion of Shadow builds have more burst damage in short fights, by replacing every, or every other lotus with a Heartseeker instead of every third lotus)
FS Burst Rotation
IoS Burst Rotation
*FS burst does get 5% more damage for the end of fight HS spam, but the IoS rotation is comparable if not better.
