Demonology Mastery + Imp main pet?

[Kethcup]

May not seem good but Imp deals very gross damage at high levels (higher in demonology since you should "normally" be using Felguard which you get at 12.)

Might be a possibility for a decent level 10 build (specifically Mastery/Vers stacking to empower your imp), maybe with tank trinkets to stay alive and resummon imp.

I might try this out. Too bad 10's can't get all the cool kids Summon items like the 15's have.

I've been doing this on my 15, I initially used Felguards like everyone else, but it's much weaker unless cleaving.

Imp hits 500 fire bolt crits.
