Not sure if its just me or if anyone else noticed but I think I managed to reproduce a bug with soulburn, if I use Seed of Corruption (or any other ability affected by soulburn) and then straigth after completing the cast press Soulburn the cast I just finished will use my soulburn and thereby I will be soul swapping my dots off the target instead of putting a whole new pair of dots on the target.
Anyone else this happened to? Its an extremely frustrating bug that nerfs DPS by quite a bit
