When I was first learning about playing Guardian, I always heard people say that I should go for the sp1 and then the sp2 for shorter fights, and for longer fights, I should go for the sp3 to build charges and then launch a massive sp2. Everyone was saying this, so I never really questioned it... until now
https://youtu.be/dXTuG07afA8I ended up finding that for a damage rotation, the sp3 rotation isn't the fastest for longer fights. This is primarily because of that long special 3 animation, but the results were definitely surprising.
Before people jump to disagree, there are a few things I want to clear up. Even though the sp1 to sp2 rotation yields better damage in shorter bursts, there are definitely times where the sp3 rotation will be more ideal. For example, fights where you want 100% uptime on your armor up buff for its utility, and fights like selective timestream where you need to burst the opponent down quickly.
In other scenarios though (and especially when unawakened), I think the community may have jumped the gun in prioritizing the sp2 damage burst for longer fights (although I could be wrong).
This isn't 100% tested (I've done quite a few rounds to support this hypothesis) so I'm curious to hear what you all think
