AoS Tzaangor equipment

[Canas]

I've just build a bunch of Tzaangor, and they have rather a large amount of special equipment.
In a unit of 10 you can have:
1 Leader
1 banner carrier
1 guy with a horn
4 great-weapons
2 Mutants

Leaving 1 whole model that's just "normal".

So I've been wondering, what kind of equipment do people tend to use? Using all of the special stuff seems far too much.

Not Sure about the mutants but i guess all the other stuff is actually used by those whacky beastmen, i'll ask a tzeentch Player Later Today about it, he plays a 2k tzeentch tzaangor list
