I'm currently running 5 paladins to use in PvP (daggerspine) but i'm running into a lot of problems. One single psychic scream or intimidating shout can knock me out completely. It's impossible to log all of my buttons to only hotkeys 1 to = (the first 12 on the toolbar) so I'm having to press shift + 2 to switch to another toolbar to use things like hammer of justice, which is very inconvienient. I'm also confused as to what spec to use and so on. Currently they're all holy. I'm playing in the 40-49 bracket.

Does anyone have advice?
