Did spirit wolves get nerfed?

im might be paranoia over Bliz not so loving the class in general, but from my observation in bgs and hitting target dummy, i realised my passive heals have been rather infrequent compared to before.

when i check my combat log however, i realised whenever the wolves makes a melee damage, it does indeed heal over a 100%++ of the damage made.

this has however made me think that the melee swing of the wolves have been slower than usual.

can any enhance shaman try this out and tell me im wrong. i dun like this feeling.
