Well, I didn't have to add a new category after-all lol. I found the reason why my recast delays weren't working. It was because I was using recast timers similar to actual disc reuse timers. Some of them were 20 minutes or more. And in seconds, that is 1200.

I looked at recast delay settings in the source and I found this:

MobAI.cpp

void NPC::AI_Event_SpellCastFinished(bool iCastSucceeded, int8 slot) {
	if (slot == 1) {
		int32 recovery_time = 0;
		if (iCastSucceeded) {
			if (casting_spell_AIindex < MAX_AISPELLS) {
					recovery_time += spells[AIspells[casting_spell_AIindex].spellid].recovery_time;
					if (AIspells[casting_spell_AIindex].recast_delay >= 0){
						if (AIspells[casting_spell_AIindex].recast_delay <1000)
							AIspells[casting_spell_AIindex].time_cancast = Timer::GetCurrentTime() + (AIspells[casting_spell_AIindex].recast_delay*1000);
}
					else
						AIspells[casting_spell_AIindex].time_cancast = Timer::GetCurrentTime() + spells[AIspells[casting_spell_AIindex].spellid].recast_time;
			}
			if (!IsEngaged())
				recovery_time += RandomTimer(2000, 3000);
			if (recovery_time < AIautocastspell_timer->GetSetAtTrigger())
				recovery_time = AIautocastspell_timer->GetSetAtTrigger();
			AIautocastspell_timer->Start(recovery_time, false);
		}
		else
			AIautocastspell_timer->Start(800, false);
		casting_spell_AIindex = MAX_AISPELLS;
	}
}

And I simply changed the check for < 1000 to < 10000 and now my recast delays are working perfectly. Here is the change I made, highlighted in RED:

void NPC::AI_Event_SpellCastFinished(bool iCastSucceeded, int8 slot) {
	if (slot == 1) {
		int32 recovery_time = 0;
		if (iCastSucceeded) {
			if (casting_spell_AIindex < MAX_AISPELLS) {
					recovery_time += spells[AIspells[casting_spell_AIindex].spellid].recovery_time;
					if (AIspells[casting_spell_AIindex].recast_delay >= 0){
						if (AIspells[casting_spell_AIindex].recast_delay <10000)
							AIspells[casting_spell_AIindex].time_cancast = Timer::GetCurrentTime() + (AIspells[casting_spell_AIindex].recast_delay*1000);
}
					else
						AIspells[casting_spell_AIindex].time_cancast = Timer::GetCurrentTime() + spells[AIspells[casting_spell_AIindex].spellid].recast_time;
			}
			if (!IsEngaged())
				recovery_time += RandomTimer(2000, 3000);
			if (recovery_time < AIautocastspell_timer->GetSetAtTrigger())
				recovery_time = AIautocastspell_timer->GetSetAtTrigger();
			AIautocastspell_timer->Start(recovery_time, false);
		}
		else
			AIautocastspell_timer->Start(800, false);
		casting_spell_AIindex = MAX_AISPELLS;
	}
}

I don't see any reason why this couldn't be added to the source updates. I am not sure why the current limit was set to 1000 or less. I guess it wouldn't even apply in most cases, but disciplines for pets and NPC encounters that might last 20+ minutes could be effected by this.
