Step Advance/Dive Roll invinciblity stacking fior HU/FI and RA/GU

[D-Inferno]

If a HU and FI/RA and GU tree both have Step Advance/Dive Roll at 3 points (.11s), does your invincibility time become .22s, or does it stay at .11s?

This question is ooold. I think everyone is assuming that they wouldn't stack, but I don't think anyone has sacrificed a skill tree to refute or comfirm the claim that it could stack.

Well... although combining Step Advance of HU and FI is really, really, really stupid (For non talking about Dive Roll Advance and because you don't really need it), it should be stackable, at least IMO. Why? Because both Step Advance and Dive Roll Advance, although is the same skill for those classes, don't forget that these skills increase the time while you use Step Advance and Dive Roll Advance, so it must be stackable.
