Sitrep isn't a crutch. It's something that contends with crutches that other players use (motion sensors, IEDs, etc). Also, I never said anything about this game being Halo. It's an unrealistic military twitch shooter. If you think it's realistic, you are delusional. Realistically you couldn't run around with a sniper quickscoping and no-scoping like it's what the sniper is made for. Also good luck drop shotting and scuf jumping in real life - especially with an LMG or sniper.
IEDs are a crutch as they remove map awareness for snipers and campers. They also allow random kills and are easily placed on a spawn.
