Spell SPAs change for procs

[Stonewallx39]

Reading through patch notes and wondering if someone smarter than me can help decipher the aggro changes. Do these effect characters that cannot cast the spell (Warriors)?

Also what’s a SPA? My guess is “Spell proc aggro?” But that doesn’t seem right.

Rogean: for spell SPAs: AC/Atk Debuff, Snare, Slow, Blind, Stun, Fear, Spinstun, Charm, Mez.
Rogean: The SPA above are capped at 1200 aggro, or 400 if the player is not high enough level to use the spell (Ex: Procs).
Rogean: Removed an overall spell cap of 400 aggro if player was not high enough level for the spell. This is instead capped per SPA Above

If these do affect warrior procs am I reading this right that a debuff proc (like https://wiki.project1999.com/Frostbite_(Spell from Frostbringer) might have more aggro then a poison counter proc (https://wiki.project1999.com/Infestation)?
