5 Pallies

[davidmage]

Prot paladins are fine, and are probably one of the stronger teams you can choose.

A setup of 4 dk and 1 pala is more favorable in most encounters. DK are superior in withstanding magic damage, and the battleresses can make the difference between managing a hard boss or not.

I haven't played DK myself in a while, but if they still have those mass grips (dragging all mobs to a single spot) it should be very helpful to handling large packs of mobs (it should also work as a wide aoe interrupt if you yank a mob, which paladins lack). That could be really essential if you want to be doing timed mythic+ runs, and have to fight a lot of mobs at the same time just because of the speed limit.

EDIT: Paladins do have the tier 3 talent, where we can choose Blinding Light. That can work as an AoE interrupt, and even give some time for your team to recover if a pack is overwhelming. Seeing especially for timed runs where you don't have time for repentance CC, this talent could be worth sacrificing at least a couple of repentance.
