Tanking as SR

I'm looking to get more information on Super Reflexes as a tanker set. I'm assuming getting the normal softcap (45%) is easier as a tanker due to higher defensive numbers. Once those are attained, with IO's, should I shoot for the Incarnate levels of defense (59% I believe?) or should I look instead into buffing up resistances to stack with the scaling resistances from the passives (or just have two builds, one for Incarnates (higher def) and one for everything else).

Also planning on taking Staff Fighting as the secondary.

I've yet to see any IO's give any decent resistant bonus.
You are better off with tough, plus, if you want incarnate softcap, throw in a 3% def/res IO, add weave (you already have tough).
Just using lvl 50 def IO's (via mids), that puts you at 52% melee/aoe, and 47% range.
3 slot combat jumping and you are at 56%/51%

I like kinetic melee (-dam debuff), to make up for your lack of resistance (what I'm currently playing, lvl 30). put 6 slot guassian in power siphon. 58%/54%.

resistance wise, the ONLY IO I see worth anythign is scirroco, 3 set gives 3.13% dark (only) resistance ... (ignoring the pvp 3% res io)

I'd go incarnate softcap, throw in aid self (cause nothing will hit you, or rarely), because, just a few 3 slotted power choices (and 1 full guassian set), you will be so close. stock up on oranges/greens instead of purples (never need them).

Here's what I'd go for in order:

~60% Defense (M/R/A)
Tough (fully slotted)
+HP (as much as reasonably possible, my TW build-plan is over 2650)
+Recharge (for attack purposes)
+Regen (which actually comes along nicely from building for +HP anyway)

Void Judgement (-50% damage tree)
Rebirth Destiny (+regen tree)

I deleted my low level SR tank pending the perfecting of knowledge about the new +res proc.

But I am Guessing it will be found to be invaluable to an SR Tank if it stacks with the scaling resists. Since scaling resists kick in at % levels of Max health, if I understand them correctly, building for absolute max health may be a number two build goal, after Defense capping, so as to have as big a hit point buffer as possible when the scaling resists become meaningful.

However, I seem to recall something being posted about the scaling resists being ported wrong or not working correctly on Tank SR, has that been resolved, if it was ever an issue?

The only issue I've seen with the scaling resists of SR, is, we are using the scrapper/brute numbers. Which is fine, but the objection (only one) I've seen, should we be using the tanker numbers, ergo, they kick in at higher values.

You'll ge ta lot of +regen, naturally, with many +health sets.

Similiar to Calderone:
~60% Defense (M/R/A)
Tough (fully slotted) (also can be used a mule for the +3% def IO)
+Recharge (for hoarfrost). Ice tanks easily can hit +100% rech debuff resistance.
+Regen (which actually comes along nicely from building for +HP anyway)

Void Judgement (-50% damage tree)
Rebirth Destiny (+regen tree)
(yes to these both)

Oh, if you dont want permafrost, you can slot 3% def IO in touch, and put the 20% slow/recharge movement IO (winter something) and still hit 100% recharge debuff resistance. Ever run across caltrops as if you were ice skating? ;-)
I dont slot (as much) for +hp, since hoarfrost, accolades, and regular +hp bonuses put me within 100HP or so of the tanker cap.

Something to keep in mind: currently, SR/ for Tanks has a ridiculously low Taunt aura value - lower than WPs, which is considered to be bad. If you're going to be tanking for a team, keep this in mind, and you may want to pick up Taunt and remember to keep changing targets on your attacks.

Where can I find this information?

Currently, looking at the taunt aura effect in the numbers themselves, it looks like the taunt effect is stronger then willpower (400% versus 300% for WP). Is it duration that's a problem? (and why does it not show duration on the powers, grr...)

It is indeed the duration that's the issue. I don't know why the ingame info doesn't show this, as it's the most important factor in taunt strength. In fact, I'm not even sure the magnitude actually *does* anything. Anyway:

SR taunt aura

As you can see, the taunt aura has a whopping 1s duration. That's even worse than willpower's 1.25s. Since the strength of a taunt aura's effect on the AI's target selection is directly proportional to the duration of the taunt, this makes SR and WP tankers' auras *much* worse at keeping the attention of enemies than those of other tanks. Given that the version of the power brutes get has a proper 13.6s taunt duration, the tanker versions' crappiness is probably a bug, but who knows when it'll get fixed.

BTW: the place to go for this sort of info is City of Data. It occasionally takes a while to update when new issues come out, but otherwise has extremely accurate and comprehensive info about basically every power in the game.
