WotLK Holly priest (don't work talent?)

[Respectos]

I noticed that when using "Binding Heal," the "Serendipity" talent stacks at a rate of 1. Is this how it should be? From my experience on all the pirate servers, I remember it should stack at 2.

Comparing how things are in other servers isn't accurate. What matters is how it was in retail and if it gave two stacks with binding heal, then make a bug report.
