Old HUD is not coming back, regardless of how many time you ask for it.
The new one will be maintained and improved, especially if you can give some useful feedback about it.
1. Map boobs. That was a fantastic feature. Claims that they don't fit inside a smaller resolution screen are nothing but lies, as I've proved years ago.
2. Increase all text size so it's actually readable (idk why the new ui has such small text when the old ui was perfect).
3. Remove unnecessary lines, etc on the screen.
4. Return the old targeting reticle, it was perfect.
5. Add a 'weapon overheating' indicator in the screen's centre when a weapon is in danger of overheating.
