I should clarify that the shield AC bonus is an unknown on P99. I haven't seen a definitive post showing that equipping a shield past the soft cap gives significant returns (i.e. effective returns via combat log parsing... cannot rely on just 'displayed AC' in your UI as it may not be accurate).
According to Demonstar55 (a very legitimate source for this type of information) the shield AC bonus came into play very late Luclin, almost PoP.
True, we use the Titanium client so it is possible this may be working, but we do not know if it was something the dev team needed to purposely enable or disable.
Someone correct me if I'm wrong, but shield AC bonus is just speculation at this point.
