You gonna share what the right way, aka your way is?
I'm going off memory so this is a rough outline.
Skills:
Basic Attack: Golem Smash
Core: Blight (I forget which upgrades)
Ultimate: Army of the Dead
Blighted Corpse Explosion
Decrepify (only one point allocated)
Raise Skeleton/Skeleton Priest
That's right, I have no actual basic attack. Seemingly every summoner you can watch just slops their golem button in their skill bar and loses the ability to cast something else. Usually a curse. This is foolish. There are enough skills to generate corpses that I don't need to use decompose, and I don't need reap because my Boner Army is my attack. And I make my damage bonuses through things that aren't Vulnerability. I generate essence by blowing up corpses.
Important Passives:
Shadowblight (this is basically always procced for a nice damage boost)
Skeleton Boosts: A bunch. Damage, limits to how much they can get hurt per hit, etc.
Golem Boosts: Ditto
Generate Essense By Popping Carcasses
Hewed Flesh
Fueled by Death
Amplify Damage
Terror
Bonded in Essence
Hellbent Commander
Important Legendary Aspects:
Boosting number of Skeletons and Mages
A thingy that sucks enemies into your Blight
Shadowblight boost
Skeletons deal more damage for being alive for over 10 seconds
I think I have one that reduces my damage taken by 15% per type of minion? So 45% reduction for the full army?
That's what I can remember right now. I don't know where I get it from, but my minions get damage bonuses against slowed/crowd controlled enemies. Not gonna try going into Paragon board.
So, order of operation is I walk up to enemies. I curse them with decrepify, which reduces their output and slows them so they take more damage and also activates that 9% amplify damage boost. Then I blight them, which sucks them all in and slows them again which I believe stacks the crowd control damage boost. Blight usually makes them start dropping corpses. I raise one for the skeletal priest, to get a 30% damage boost; by now Shadowblight is in force too. I pop the corpses for the blighted dookie ponds. Everything melts. If needed, I can send my Bloodbag Golem in to do his smash, that's my basic attack, otherwise I save it since it has 16sec cooldown. Blood golem is basically unnkillable and reduces damage you take.
Skeletal Priest is a massively underused skill by summoners and it's probably the most important skill for them; second most important is ditching your basic attack for the Golem Smash so you can have a curse; I think that's something like a 49% damage boost right there or something. Watching streams, it drives me insane how nobody uses the priests. They wait until their skeletons are dying, then they start raising new ones. With the skill that doesn't let them lose more than x% of health per hit, and skeletal priest using the heal perk, you can pretty much always keep your skeletons alive and at a sizable chunk of health. Pop "raise skeleton" on a corpse every five seconds, and you keep a steady huge damage bonus and at the end of each 5 seconds the boners are healed. Also, I think you can only have five blighted corpse pools active at a time, since they stack. so you can pace corpse consumption.
For boss fights I will start with Army of the Dead to do damage, and also drop starter corpses. After that, if the fight is still going on 40-50 seconds later, I'm only using it to replenish my boner army if I lose control of keeping them alive.
I use skeletal reapers to make more corpses on top of what my blight churns out, and shadow mages because my whole thing is built towards bonuses from shadow damage.
I have left things out. But this is the way.
Edit: And I pick equipment based on boosts to the important skills.
