Arcanist/Summoner melee pets ignoring Egi Assault II cds for endless Ruin IV procs

Date & Time: 29/10/2019
Frequency: Always
World name: Leviathan
Character name: Nemekh Kinryuu
Retainer name: Naubi
NPC name: N/A
Monster name: N/A
Class/Level: ACN/SMN
Party or solo: Party
In-game time: N/A
Area and coordinates: Any areas with combat
Housing: N/A

Steps:
1. Summon a melee egi/carbuncle (Topaz, Ifrit, Titan)
2. Target an enemy
3. Enter combat, but put your pet on "Steady" so that it does not get into melee range
4. Have at least 1 charge of a PBAoE Egi Assault II (Flaming Crush, Mountain Buster) that results in Further Ruin for Ruin IV
5. Spam press the Egi Assault over and over but do not let the pet hit the enemy with the action
6. Watch as the pet spams the Egi Assault on the spot over and over, ignoring the Egi Assault charge cooldown and you gain Further Ruin stacks over and over

Please see the clip from my stream with this in action

This is reminiscent of the HW era Sic exploit that I reported several years ago. It does not work if there are no targetable entities and as a result has limited combat applications, but is still pretty absurd and is very much broken behaviour.
Edit: Apparently when a charge is spammed before a boss jumps, you can get back up to 4 stacks this way. This likely will matter on e3s and similar encounters.


Potentially related, it is apparently possible to dupe Ifrit and Titan enkindles. Ifrit by enkindle being at the tail end of burning strike's cooldown, titan where using enkindle immediately after initiating the rock buster cycle with sic. Clip of double infernos from Ishtar @ The Balance.
