You get stuck on a location with only one entrance (lets take example of like a tower with balcony), somebody blocks the one entrance and refuses to move. Now, there is some "balconies" locations that provide you an option to fall slowly down, tho taking damage during the time falling slowly, due to height. (see example of what I mean) Now, why this isnt in danger situation, as you cant do crap, the person blocking enteance can just shoot any time to take oyur most of HP before you react and you cant do anything bout it. If this isnt in danger situation, its most bullshit thing ever I seen. (here is example from one of minecraft maps: https://imgur.com/a/jOofXt2)
No. Same with blocking doorways in any other situation. Just type @stuck if there is staff on. Shooting them is RDM.
