Just going to be a written version of the video above showing you how to use Implosion in a sustained AoE scenario or in a 2+ target AoE scenario.
- Cast Hand of Gul’dan
- Generate additional Soul Shards
- Cast Hand of Gul’dan again
- Immediately cast Implosion
By doing this it implodes your oldest set of imps while keeping your new set alive for your next round of implosion.
Rotationally this method of using Implosion is fairly smooth, but does require a certain level of latency so that it doesn’t fail and implode both old and new sets of imps.
