I'm hijacking the thread a bit! I'm also returning to WoW after many years away, returning for the PVE (when before all I did was PvP)

I actually got excited to try and clear all of the 5 man content myself with a completely multiclass, multirace party.

As I look at what looks like every single Legion pve video, they're all running 5 same class compositions, or maybe a 4 same, one healer combination. They also all seem to be melee.

Are multiclass groups not do-able in legion? I was thinking of a warrior tank with a druid healer, mage, elemental shaman, shadow priest. Are ranged DPS no good in Legion? I don't mind a challenge, but if it ramps the difficulty from "really hard" to "near impossible" I won't even give it a try, and I'll do something like a 4dk Holy paladin combo. I just always wanted an eclectic team of all different classes and races, but the lack of seeing videos of it makes me assume it's basically impossible.
