1) That is why i think it should be capped at 50%. It was always fine around there. It did start to break down with multiple SBs and other contributing powers.
2)This doesn't really change anything. Good info, insanely hard to test. I've been trying to get a Tsoo to siphon the speed of one of my pets for hours now. But again, doesn't change the fact I think they should be getting 50% recharge buff.
3)@Unknown: I don't know how many MM/kins you've got to 50 and really tested out but currently I have all but beasts done. All of them so far miss 90% of FS which is kind of a focal point of kin. A lot of them never position themselves to get transfusion or transference so there are 2 more great powers that are more meh for MMs. Speedboost does give them end recovery, but that is not needed on MM pets, other than ninjas. The speed increase actually ends up getting the pets stuck in walls constantly so not only is it not buffing MM pets, it is causing them problems. ID is actually great. AM comes back to slow and doesn't add enough damage to pets to make it great. The anchors on rad are way too heavy for a lot of the MM primaries. Several of the lvl 18 powers have a fast recharge but cost a ton of end. It just so happens that it lines up so that the defense based sets that you would want to pair with Rad since it does ToHit Debuff are the ones you need lots of end to play, bots-ninjas-beast. None of rads later powers were adjusted to be applied to henchmen or some sort of modification to make them more effective for MMs like they did for other sets. Time Manip, I've not got a chance to get every MM primary high level with time. And while I love the healing it can do, the fact that everything is based off of temporal selection which is barely a buff to a pet at all means you'll never be able to focus on healing your pet without losing out on what could be happening by buffing others you hopefully have on your team. Time is by far the most I've felt I needed to be in a large team to even play. MMs in my opinion should be pretty good at solo play. I don't think I'll ever take Time to seriously on MMs because most of the sets buffs don't work well with pets. Also not having a main targeted heal means it is sub par for everything but bots. To those of you reading this, make a Bots/Time MM. I bet they are really good.
In conclusion due to the factors I've stated above, I would call those power sets crippled, and since I am at least someone, I'll have to disagree with no one thinks like I do.
