I think the problem here is that some people think there is a "fix bugs" button somewhere that we refuse to press. It's not that simple.
For example, the angle mod. Prior to introducing this feature, heavy tanks were useless, because you could simply aim for their exposed weak top and kill them in one shot. The angle mod fixed this perfectly. However, this does mean that if you aim at the centre of an enemy tank and you hit the top of the hull in front of the turret at a low angle, you will do no damage, even though you were aiming straight at the tank. This is an unavoidable side-effect of the angle mod and while unfortunate it is not as bad as it was prior to introducing the angle mod. So this is a concious decision we made. "angle mod bugs and random penetration" is not a bug that is fixable. It might be possible to reduce such occurrences by redoing all collision meshes with the angle mod in mind, but this is hundreds of hours of work and no one is willing to do that.
The same goes for the turret rotation. Prior to introducing the rotational speed limit in 2.45, players could set their mouse sensitivity really high and move the turret of heavy tanks around in seconds, while really it should take minutes. To prevent this exploit, we added the rotational speed limit, but as an unavoidable side-effect it makes the turret slide on if you move it around too fast. This is not something we can fix without disabling the limit altogether and we made the concious decision that the mod is better with the limit.
You might not agree with these decisions, but to me, that is irrelevant. And I have to say this is my personal opinion that I'm sure many other developers don't share. But I don't think about what you might like when working on Forgotten Hope, I think about what I would like. And not all developers agree with each other on everything, in fact, it might be more accurate to say that there isn't a single thing in this universe that all developers would agree upon. So each development change is the result of hours worth of discussions, concessions and compromising. If people who don't even contribute to the development would have a say in things as well, I would not want to be the person in charge of that chaos.
And finally, there is no need to complain about your problems in every single post you make. Yes, we read the forum, yes we know. This constant whining is just very demotivating, especially if you're dumb enough to take the time to reply to it.
