Pets in missions (not MM) and XP

I have one surviving MA arc. It has a ton of underlings in it to be rescued, who will then fight for you.

The main goal was to make an arc that a low level squishy could do.

Now, my memory is lousy. Really lousy.

But I didn't recall that you lost XP when the pets did damage. Has it always been that way?

Your own pets from primaries, secondaries, and some temps don't but MA pets will count as allies/teammates instead of pets and thus the XP drain.

Thanks.

Really shows how I lost touch with the MA over the last few months.
