Need your advice for summoner (spectre / skele mage) hybrid ?

Hi there. So I made a summoner, a terrible one and I want to improve him a bit and I think I need your help.... kinda :)

Normally I stop playing the character when I reach the first T10 map and only made it to awaking level 3 once.

Here is the past bin, I haven't set any configuration, it is just the gear, gems and the passive tree.

I have to work on more armor to get to 75% phys cap (currently 68%).

I don't wan't to play without "unwavering stance" (can't evade attacks, can't be stunned).

I have mage skeleton (mage because of a jewel) and specters (syndicate operative) both in the same armor while using a physical curse and hatred (xy% phys damage as extra cold).

I'm a bit lazy and don't want to summon skeletons for every mob. I only summon them in big fights like ritual, archnemesis or boss encounters.

It is working okay for maps 10 and below but could be better, currently working on a 20% minion helmet (need to roll life) and 20% minion damage hands.

Some bosses are way to tough and it takes forever.

Normally I use baronite preachers after reaching the first maps and use Wrath (lightning aura) and Conductivity curse (lower light res) but in patch 3.17 I haven't see anyone yet... so I was trying to go full physical this time.

Any suggestions ?
