In my experience All Prot is very very strong for pallies, but also a bit boring. You can mix ret in if you like, but it's challenging to outdo your prot DPS as ret, especially in large groups. Going Seraphim w/ your prots can be a nice boost too, but slightly tricky to manage. "Last Defender" x 5 can be seriously OP, but only if you're making crazy big pulls (I.e. Kara mount runs). The math is a bit nuts: https://www.reddit.com/r/wow/comment...ld_never_tank/
