Come on stop this trashtalk. The topic is quite interesting and not worth to be spammed with this rubbish.
I don't not even think that it's that low priority to make a gun work properly, that is AT and AA at the same time and on very many maps. I don't mind if the size of the shield is currently a bit wrong, I'd just like that there is a solution that makes 88's with shield able to perform well as AA gun, for example by moving the sights closer to the shield so it does not worsen the view that much anymore.
Don't forget that 88's are often simply base defenses and won't ever see a tank, because of ABC lines or because they are behind a hill or at some position the enemy can't be seen at all. When they then also have a shield attached, then they are just decoration on a good bunch of places, as the 88's with shield really can't be accepted as proper AA gun currently.
Not like high priority, but I don't think it's that low either. It should be a point on the list in my opinion.
