Is your feature request related to a problem?

It would be nice if Focused Ballista Support could "trigger" supported ballista totem skills, limiting their attack rate the same way that Asenath's Chant or similar effects limit the trigger rate of spells based on the attack speed of the triggering skill.

Describe the solution you'd like

Adding Focused Ballista Support to a skill group should cause ballista totem skills in that group to have their attack rate limited to the attack rate of a "triggering skill" that is used by the player, subject to the same effects as all other triggers in PoB (missed trigger intervals reducing the trigger rate, warning when no trigger is found, etc.). This would of course use the totem's attack speed as the limit to the trigger rate, as opposed to other triggers that use an internal cooldown.

Describe alternatives you've considered

Currently, to calculate true DPS from ballista skills supported by Focused Ballista, you have to do all of the trigger rate calculations and comparisons by hand.

Beginne damit, die Verarbeitung von Focused Ballista Support und die bestehenden Trigger-Berechnungen in der Lua-Codebasis zu finden. Vergleiche, wie die aktuellen Trigger Begrenzungen der Angriffsrate, verpasste Intervalle und fehlende auslösende Skills behandeln. Erledigt ist die Aufgabe, wenn unterstützte Ballista-Totems die Rate der auslösenden Skill verwenden und dieselben Warnungen und Ratenberechnungen ohne manuellen Vergleich bereitstellen.
