Gonna say no (and HT even said he did this on purpose so I don't see it being changed). I say 'no', because not all of us use it to be dweeby. If I'm being chased by 5 cons when I'm wounded (such as a wing missing, or engine out) and I manage to land it safely on the ground....I want revenge on those hording dweebs....which is worse really, 5v1 or 1 person in a tail gunner on the ground? If your wish is to disable the gunner on the ground, my wish is to make any planes that jump my wounded rtb plane in gangs of 5-8 to explode when they get within 800yards.
Heck I almost never use the gunner, only times I really do are: When PWed and blacked out and when I just lost vital parts and am now stuck on the ground....if the person is stupid enough to stick around before I have a chance to bail, heck ya I'm gonna shoot his little German plane.
Question, on a more serious note:
I've never actually seen it used in the ways some describe (landing, killing, re-upping to land kills), so is it really that hard to see/avoid a single .303 firing? I'm curious since I crashed to the edge of a little furball going on and was spotted immediately by Klingan at a range of over 1K away (outside effective gun range).
