How so? If I can hole myself up in a room, perhaps with a few mines, maybe some teammates and watch people continuously blunder in and die then that's tactical not cheap. Perhaps they should use tactics to oust me? A few grenades perhaps or just simply ignore me and bore me out if there. But no, they keep running in desperate to kill me knowing they're most likely going to get caught in the crossfire.
@djronz. Its just a cheap way to get kills.
