Invuln VS Super reflexes

Another way to think about it to is this. SR has slow resistance (which is wonderful) and faster movement with Quickness. Inv has 2 "oh noes" buttons, Dull Pain as many have mentioned, but don't forget Unstoppable (yeah the crash is nasty).

I have an Inv tanker and a SR scrapper. The SR can do insane things, but it really only takes a few bad rolls to wonder why I am in the hospital. That can happen with Inv, but you usually see it coming from Psi damage, so you can try and avoid/prepare for it.

I like both advantages to be honest.

Edit: I haven't had my tank in a trial yet, honestly haven't touched him much since IO sets came out (going to soon though), but on my SR in trials I find myself at 87%-ish a lot to all positions, at least once I was 153% to all. That being said, and depending on the members of the League, Inv is going to gain a lot more from buffs in trial, imo anyway.

A small update on my SR tanker; last night I was playing with a friend's StJ/Energy Armor brute and noticed a disturbing trend. I was first into melee and had the mobs clumped tight then he'd attack and I'd immediately loose about half the spawn. I've NEVER seen that happen with an Invuln tanker and I conclude that the SR taunt aura must have gotten the Willpower treatment; it doesn't appear to hold aggro well.

After a couple of missions I grabbed my StJ/Invuln scrapper and had no difficulty holding aggro from my buddy. Mid's claims MAG 4 on SR's aura... seems like the Dev's set it's duration extremely low. I do notice Mid's mentions a 1 second duration for Evasion (the taunt aura/AOE def toggle) and a 0.75 second duration for the other toggles. If that's true then SR is actually worse than WP for aggro.

Well, I tried SR and so far I'm loving it. I joined an Admiral Sutter TF a few days ago at level 22, SK'd to level 40, and managed to hold the aggro on BOTH Duray's on my own - only died twice.

Funny thing is, we had another tank along to help, but the little b**ch had an uppity fit and left us in Skyway after causing our debuffer to ragequit the TF... With 6 people and only my Tank as a Melee, it took us 25 minutes to finish the TF, but damn, I never felt more heroic ! Frankly, I amazed myself with how survivable this set combo is. May not be "Master of" material, but definitely a fast and fun ride !

As a counterpoint to the "you get buffs in itrials", I'd like to say that as someone generally playing quick, although not overly so, I almost never get buffed to the extent that I consistently go from normal softcap to incarnate softcap in certain parts of the trials. Initial warworks phase and pulling Nightstar/Siege in BAF, pretty much everything in Lambda up to the final fight, pretty much everything in Keyes up to the final fight.

Taking the aggro first and fast can be important and helpful, letting squishies who are as fast start doing their own thing instead of having to wait for some slower-paced people (... as well as preventing the squishies who *will* start their own thing anyway to scatter everything to the four winds with a freezing rain or something and no other means of taunt/slow/immobilize) ; and in a league, at least the numerous PuG leagues I've been in, there's huge inertia, people all standing around looking at each other until someone finally decides to move in after 10, 15, 20, sometimes 30 seconds.

With that mindset and playstyle I've seen a significant difference between 59% def and merely ~45-50%. My incarnate softcapped SR brute had significantly higher survivability than all my other alts even starting out without level shifts.
