Outlines on BTB

Sniper glare is enough to give away your position, but a huge, really noticeable red outline giving away your position is not cool while playing BTB. This breaks any stealth play in this game. I can tell 343 wants players to engage more in firefights, but anybody being able to spot you 3 Km away thanks to the red outline is just too much. 18 meter radar and infinite range in enemy outline detection is just contradicting/dumb/wrong (I could use another word to better describe this, starts with an S) Anyway, am i the only one that feels this? Feels like enemies have some sort of wall hack/enemy detection hack. How do you guys feel about this?
