picture this--
You and your wingman are in a hot one with a skilled pair of pilots. The battle started at 25K and has lasted it seems like several minutes, bot pairs jockying for position. You score hits on one of them hes smoking but hes also on your wingman tight, with his wingy zooming high to gain position on you. You give the call for your wingy to break to avoid the inevitable fire. On que he does, with the enemy turning with him as planned giving you the close range deflection shot you wanted. He fills your windscreen with his AC, You press the tit, nothing!! Gun jam, its your turn in the bucket. He goes on to shoot down your wingmana moment later, ending a 50 sortie streak without a death for him--with nothing you can do but watch. You split esse over to extend to your base but alas all you have is yourself and you AC's speed, which will not get you out..the enemy duo claims you too.
Thats the way I see gunjams.. you can keep them. As long as there is really no viable way to escape unseen ( ie...like in reality without neon icons..inflight dar...) then gunjams would not be an asset but another source of endless wining

now I know that may be a little more than 2 cents..but I thought I would give it anyway
