I haven't notice this bug so far. However, I have not really payed attention to if I get a heal every single time a light/heavy attack is used either. Still I feel it heals me consistently though.
Keep in mind that Medium Attacks, including the channeled ticks of restoration staff and lightning staff heavy attacks (not the final hit) will not heal you.
If you were weaving medium attacks in between your Force Pulse casts then this is why you weren't getting any heals.

That´s the only thing that can explain it. Personally I think medium weaves should be included into the heal
