This gonna be my first HC character and I prefer survivability over dmg. I plan to build something like this: http://www.grimtools.com/calc/RZRABG9V , but I dont know if its gonna be any viable at Ultimate difficulty. Currently lvl 14 with 1 rip at lvl 15 
Any tips and hints will be more than welcome.
Tanky AF.
All I’ll say is most of the elite Tac builds use Inquisitor Seal, which you’ve swapped out for maxing the soldier defensive passives. I’m wondering with slightly different gearing / devotions if you could change that.
Imo if that’s a phys dmg build then Witchblade or Commando or maybe even Deathknight. Tactician is biased towards pierce damage.
There’s nothing stopping you from doing a pierce tactician: http://www.grimdawn.com/forums/showthread.php?t=52683
I don’t know if that build is suitable for hardcore though, never played it.
