I will go on to give more tips/suggestions for my build or another pet orientated variation below.
So basically; for passives I am recommending Blood ritual + fierce loyalty + spirit vessel*
(first 2 should be obvious from above; spirit vessel is the best 3rd slot; because it gives you more mana back from spirit walk (via shorter cd) and is a free death for that time you go afk or trying to eat a hot pocket at the keyboard. I think honored guest spirit walk rune should most definitely be paired with it because of the bonus of getting 30% mana back 2 seconds sooner.
The flexible part in build is hex; personally I like the set and forget CC, ability to have it heal myself, my pet(s), or party members; and 10% extra damage to the chicken can't hurt! Other good options would be sacrifice-pride (i personally dont like it thought because if i hit it on accident soon after summoning them it hurts my heart to go 30 sec without.
Lastly, Burning Axe of Sanki's (my most recent item purchase) seems to work great with fire bomb (and for that I would recommend roll the bones rune; because nothing else can give you 3x aoe explosions per cast (even if 1-2 bounces hit 2-3 target each on average; still great compared to 1 cast of other primaries (besides rot mainly) leading to a more confined damage range. It's also great fun to try n set up for a double hit on a monster with it by being pretty close and "bouncing the basketball" right between the monster and you; ideally it should land on his nose 2nd bounce and 3rd bounce his !@#. Although not always feasible, definitely makes gameplay more interesting when you can look for opportunities to multiple your effective DPS like you can with roll the bones rune!
Oh, btw I only have ~43k dps (no buffs on it though) and I can clear white mobs in 1-3 fire bombs and elites in <60 sec usually a good amount less ( Act 3 inferno ). Having dropped from ~60k I really don't notice too much diff in current content speed (although maybe the 16k thorns is more then compensating)
