the system is perfect. you dont pug them. if anythign goes wrong, its up to you. dont have friends? make them or leave wow.
have you done a decent mythic+? add that ppl and ask them for play when you are in another. 2?3?4?5?6?7? decent groups? add all of them, just broadcast the key and you could get decent lol.
Its a team challenge, if one of your team leaves, you are screwed, how its supossed.
