Low level tanks (pre-tank stance) have a very hard time holding threat after the nerf

[Noxifer]

The main issue with blaming this on the Vit and str changes is the fact that is actually has barely any effect on early tanking

You cant tell me that if these new tanks that are losing aggro tanked the same way in the same gear they are now before 3.2 they wouldnt be losing aggro just as fast

It's not only the Vit and Str changes. It's the over-all lowering of tank damage -- provided you weren't in full Vit accessories, something low-level tanks won't be pre-30, because there are no Vit accessories until you hit 28 (apart from one puny bracelet at 19). Yes, it's "only" 10-20% dps loss (I don't remember the exact numbers anymore), and that's not that much at those levels, but it's still enough that it can make a difference for someone learning the class.

I started both a fresh MRD and GLD for 3.2 and did not have problems.

When playing as a DPS, some tanks held threat, many didn't. When playing as a DPS with an experienced tank buddy of mine who started a new tank, there was no problem.

Yeah, the key word is "experienced", I'd say. And even if you hadn't played any tank jobs before, you've still been made aware of the issues while levelling healer. (It's easier to not make mistakes if you've seen other tanks make those same mistakes over and over, after all.)

Like you said, I agree that tanking has one of the most difficult learning curves. I'm not saying the math doesn't allow people to hold threat, I'm saying it makes it more difficult than pre-3.2 for low-level tanks. And since the majority of low-level tanks are likely to be players who are entirely new to the class, it's my opinion that SE probably should have tried to figure out some way to help boosting aggro for low-level tanks instead of relying on aggro boosting via tank stance to alleviate the (potential) dps loss.

(I'm also fairly convinced that they made adjustments to the level synch math that makes you stronger when synched down compared to pre-3.2. I can't prove it, but it feels like we've been burning through things a lot faster when we've gone into stuff with a full, synched party than we used to. And if they did that, that makes it even more difficult for new, non-synched tanks when they end up with synched DDs.)
