In my opinion, Tactician has the same problems that Mage Hunter has: Soldier, Inquisitor, and Arcanist all have a truckload of good skills to invest in, but it’s extremely difficult to get all the skill points necessary to invest in all of them, leaving to very unoptimized builds compared to other more synergistic classes.
I created a Ranged Cold Cadence build during 1.1.9.0 here:
That uses the older stalwart of 22/12 Seal, 21/12 Censure, large life-steal and Ghoul. It attacks fast and does the job, but straight Cadence - even Ranged Cadence which pierces enemies - can’t carry a build on its own. Yes, build standards have changed, but a lot of other classes got a huge buff to either passive damage or can activate multiple procs which dish out a lot of supplementary damage.
Can’t say for sure whether it’s the weakness of Ranged Cadence, weakness of Inquisitor ranged WPS when not paired with Fire Strike, or Seal + Censure just needs to do more offensively than what it does now - which is basically 36 points for some flat absorption + damage reduction, negligible amount of flat damage, and RR.
