Mastermind experts on end reduction?

I would be happy to get one of these answered, no need to try and answer all of them if nobody knows.

On my thug/pain, all the thugs are running out of end, which is fine for the most part, but i'm wondering if end reduction would be worth slotting.

I'm using these in pvp, and sometimes a fight can last anywhere from 5-20 minutes. The pets will run out of end fairly quickly. So my main questions are...

1. To start off, the dmg/end enhancement from Soulbound, does that affect their end reduction? I've heard something about the 'end' part of the IOs not working, and i would need to use regular invention IOs or SOs...or HOs.

2. Will the enforcer's leadership ever turn off because they ran out of end?

3. How effective will slotting end reduction really be? Are they at almost the same performance at full end as very low end? Would slotting end reduction only mean they have more end for 20 or 30 more seconds, making it meaningless in the long run?

4. How much end reduction would they need to never run out of end, if that's possible. Would it ever be worth it?

5. Finally, would anyone happen to know if an increase to end reduction would be more effective than an increase to damage, at any time (say....60% damage/30% end better than 90% dmg), DPS wise?

Thanks for any responses!

1.) Dam/End IOs will only reduce the end cost of henchmen powers which also do damage.

2.) Enforcer's Leadership is an Auto power, so no they won't toggle it off.

3.) Slotting End reduction will be beneficial if you're engaging in long PvP fights.

4.) Most henchmen lose their Endurance issues with 20-30% EndRedux.

5.) I would have to say no. Henchmen really aren't all that smart about DPS anyways, but a slotting situation where they're not doing optimal damage seems like a losing situation.

Number 5 depends on what sort of henchman you're talking about.

Some, such as the Tier 3s in Necromancy and Demon Summoning are useful for their controls, so not slotting them for damage won't hurt as much as with a Bruiser.

True, there are Henchmen who don't specifically deal damage, though the question seemed more directed in asking if there was a situation were "End > Dam" in slots where you would go for damage.

On that note, even henchmen that do not exist only to deal damage can benefit from slotting for it. Mix-matching HOs/IOs to get optimal damage along with desired secondary effects is a good way to go; I know that the Protector Bots add a lot of damage to Robotics if slotted for it. This is also true for the Demon Prince, and it's also important to note as the Tier 3, they're the least effected by the Purple Patch.

#3 and #5 depend on how long your battles are lasting, and how often you need to resummon pets (who cares if they're out of end after they die.) If your pet is running out of end, they're going to be dealing quite a lot less damage than if they have lots of end.

I've been watching my Jounin do this. Certain pets seem to run out more than others.

ofc once you hit 50 and unlock the alpha, a cardiac boost will wipe all pet end troubles away (so long as you don't exemp)

I haven't seen the enforcers leadership toggles drop from lack of end. Pets will use forego using some attacks and buffs if their end is too low, especially protector bots, hellfire gargoyles, and ember demons. Most of the time, six slotting the pets with pet damage sets will push the damage enhancement to 90% and the endurance reduction to a healthy portion. Demon summoning has certain endurance trouble because they have pets with abilities that don't utilize the endurance portion of a pet damage set in a heal, slow, or resistance power.

Yes, a full end redux from a generic IO enhancement can cure a lot of ills.
