As the title says: please consider removing the no-fight flag from grow/shrink premium and veteran nanos.
At the very worst have the cancel automatically when fighting engages, like nano cans.
If the social tab's reasoning of having your weapon visible was followed: the shrinking nano does not scale you down enough for your wielded weapon to be obscured (and most of the other scale affecting items are removed).
There's no reason for these nanos to be pacifist only.
