Having played around with a heavy blaster equipped wolf, there's an odd shielding behavior I've been seeing: An enemy ship that I'm holding just in range of will keep their shields up... until I fire, at which point they decide "oops, that's too much firepower, I don't want to overload", drop shields, take the hit on armor... and then put their shields back up again, preventing them from dissipating hard flux, and perpetuating the situation.
This is something of a corner case, really... the behavior is only "wrong" when my only weapon is that one heavy blaster (and a few missiles, but it could get shields up in time if I actually fired those). But, given the wolf + heavy blaster starting option, it's a corner case that's likely to come up.
