Lightspeed --

• No windup. No counter-play.
  
• Long-ranged.
  
• Can be used during charges as displayed in this gif.
  
• GCDE, can be used to combo.
  
• Can be used to drop an entire spell bar of nukes from virtually any distance in the entire RPB.
  
• Unhealthy/Toxic.
  
• Teleports behind the opponent, which means skillshots and other aimed abilities will miss unless cast just after the teleport. This is enough time to be stunned and any counter-play option removed.
  
• Can be countered by having a sense of your opponent's habits and using AoE's (I guess).
  

Scattered Lights --

• No windup.
  
• No drawback to the caster. They can still walk, block, cast, dash, whatever else.
  
• Orbs are dealing in this picture 1.5k - 1.7k a tick (Rings, the closest ability, does not tick this high, crit or not). 
  
• Fires at least 10 orbs. In this captured scenario, that's a floor damage of 15k unmitigated, 17k ceiling
  
• Orbs seem to have a leeway of 1 or 2 tiles for hit registry (its a little hard to perceive due to the phantom strike happening at the same time. I experience the damage even if the orbs don't make contact with my character pretty often enough, can face it yourself or go on my word and the visual evidence of the slowmo).
  
• Contrary tot the idea that they have leeway, that means that the person phantom striking is actually phantom striking onto newly spawned orbs of light, and immediately taking the damage-- which means at least 2 or 3 more shots that are hard to account for which adds another 4500-5100 to the prievous totals, getting close to 22k off of one spell cast.
  
• Orbs go active immediately, meaning they proc for damage as soon as you can see them, unlike Rings that surround you and have a short delay before going active, meaning Rings has a windup, takes time to actually start applying damage, and offers counterplay. 
  
• Scattered lights spawn ready to burn you alive and don't attack all at once, meaning the damage is staggered and the response to said damage needs to be staggered. This can be combo'd with lightspeed and a stun to guarantee full Scattered damage + AoE damage from holy or cosmic(cosmic being a worse offender cause of the slow), or a ifrit combo, or whatever else.
  
• Random response to someone who will point out Holy AoE is stronger than Cosmic AoE: Cosmic AoE keeps you slowed to deal with more damage from the caster and to keep you on the AoE longer ticking for roughly the same if not more damage anyways. 
  

@Detective, it took me 5 tries to post this and the post kept ignoring my edits.
