mini maps = wall hacks if you know how to use it effectively. The mini map is slightly transparent so you can still view whats in the back of that. Also, when playing (esp as a sniper), you always want to be aiming at places that you are potentially expecting enemies to be at so the top right corner is usually irrelevant (and its easy to adjust your aim with your peripheral vision). However, effectively using the mini map will give you a whole ton of information that you would not otherwise be aware of. For example, location of where your teammates are, where they are dying, and the most important thing... what is currently around you (are there friendlies??). If you hear footsteps and you know you don't have a teammate around you, you know they are coming from behind you and you can now prepare and surprise your attacker instead of being surprised.
