Tanking - HP vs AC

[Sizar]

I was told by a well known and basically BiS knight that the 1100 and 1200 AC soft caps were noticeable when soloing. So during my time soloing in HS from 55-60 I made a point to pay attention to how well i was doing when under 1100 AC, over it, and even when i hit 1200 from buffs. The difference between 1099 and 1101 was actually noticeable, but I did not notice much difference of a low 1100's and just over 1200.

I would sacrifice some better hp gear if it got me over 1100 AC, felt right
