Re: 5 Blue; What's the point?
I can see both sides of the issue, here are my thoughts on the blue line.
Yes, it does not provide as much DPS as Red, or Group utility as Yellow, what it does provide is solo survivability. Traited 5b, your pet (lurker, eagle, what have you) is on par with shard droppers, you have access to your full CC suite (no reduced blinding flash, my one dislike of MoNF) and upgraded healing to keep yourself and your pet up. So instead of having to pop Call to the Valar for roots, you can stun one or two, let your pet take several more, and take one on yourself. All the while keeping yourself and your pet up through flank heals and BoH.
