That’s true about the unneeded bloodrager dip, but having played a bloodrager1/skald 10 I can tell you my feats were spoken for at every level, so squeezing in two more for skill focus/Eldritch Heritage or even just one for the wasp familiar can be a bit difficult until you hit 11 or so. Primarily because skalds can suffer Sudden Barbarian Death syndrome, having lingering performance and possibly even diehard are highly suggested.
Wasp Familiar, Amplified Rage, Power Attack, Lingering Performance only take you to 7th. You could also go Community-Minded and put Lingering off until 9th, grabbing either the Eldritch Focus line or Skald's Vigor. Also, you might be better off ditching Lingering and using Community-Minded exclusively if you have a Superstition using Skald, since Lingering can prevent key spot healing with the Skald.
Diehard seems like a particularly bad solution to Sudden Death Syndrome because it is Sudden Death Syndrome. Sudden Death Syndrome happens because you're still standing when you should have gone down, so enemies hit you until you're for real dead. Diehard is another known player killer for that same reason. I know it can prevent you from going down due to Sudden Death but it won't prevent you from going down because you're still standing in front of the thing that just nearly killed you.
I played a Skald from 3-14 and got Sudden Death'd just once. That instance, the hit was less than 10 damage away from killing me by itself - a higher roll on the damage die and I'd have been dead whether or not I was mid-Rage. "Sometimes enemies do the extra 10 or so damage needed to actually kill you (but really only at levels 6+)" isn't a good reason for me take a feat. If the feat incidentally protects from that while offering you other benefits like Lingering Performance it's definitely a bonus but it shouldn't be why you're taking the feat. I know not everyone has the same playstyle though and maybe Sudden Death is a more likely occurrence for some people, so I suppose take me with a grain of salt. We are in a thread for AGGRO support : )
A lot of you mentioned skald, and of course that was automatically the first thing that came to my mind. But considering that A. I don't know what the party comp is even going to be, and B. one of the people playing is the complete opposite of me. (skittish and worrying about everything instead of focusing on one thing) Honestly, I would not be surprised if she went full healbot support and told me to do what I always do.
I think Skald is fine in that situation. You're only slightly behind a Barb on Rage power, so just one other person who accepts the song is good enough. You still have spell buffs for folks that are worried about the AC penalty or casting. You seem to be into the idea of a Paladin, though, which is also a great choice!
