Soulbound Allegiance and Mastermind pets...
Yes I also have a few pices of this set in recipy froum on my Mercs/Traps If its not buged would it work better in my T1 or T3 pet?
They did finally fix the set to work in sub-50 pets.
As for where to put the set, I think I'd advise splitting them 3-and-3 since the 4, 5 and 6 bonuses are pretty pedestrian if you don't do much damage yourself.
I don't have much experience with them in henchmen other than verifying once that they weren't working in Drones or Prot Bots. So I don't really have any advice there, other than to agree with not using the BU proc in the Lich and Prot Bots. Though, using 3 in those pets might be useful for getting other enhancement in without surrendering Damage.

The MM pet purple set isn't the be all end all set it the way the purple set is for Corrupters or Doms. Its main use is for filling in the 'gaps' on a hard to slot pet. Enforcers and Protector Bots, for example, often have a lot of competition for slots so an extra strong IO can help a lot.
The unique is pretty decent too but due to short buff duration is better to use in lower level pets since 3 pets gives it a lot more chances to proc (pet pet has a seperate chance to proc). Its good for Thugs since they have some really strong attempts in their T1 pets.
I was considering getting this set for two of my Masterminds. (It's a long term goal. A really, really long term goal.) However, I remember seeing a list of "known issues" that stated that this set would pretty much shut down on any pet that wasn't actually level 50 - which would be all of the Tier 1 and Tier 2 pets, and all Tier 3 pets if you're Malefactored for any reason. Did this ever change, or is the set working as intended?
If it is possible to use it, the two characters I was considering getting it for are Necromancy and Bots. For the Necro, I was thinking of placing it on the Grave Knights, since the Lich seems to be more focused on debuffing than actual damage. This would also allow the set to function if I was running all but the lowest level Ouroboros missions.
For the bots, I was planning on putting it on the Assault Bot. If I understand how procs trigger, his missile swarms and AoE beam attacks would have a decent chance of getting the "Chance for Buildup" proc to fire. Alternatively, I could put it in the basic Drones, since there are three of them. (I've currently got the Protectors four-slotted with Blood Mandate, plus a standard crafted Heal and Defense enhancement. They don't seem to be damage monsters in any case, and boosting their healing and shielding potential seemed like a good idea, especially as I don't currently have any healing powers on that character.)
