Unfortunately an unwritten rule is only a courtesy and not an actual "rule". It's not against the tos to pull at any time or allow specific people to pull it. It's open world and anyone is allowed to pull when they want. Just because there's link shells and discords on NA servers for trains and S ranks call outs does not mean it's a game rule, it's just a community rule. I hunt A ranks in ARR and HW solo when I see em. I could call it out and then wait but its faster if I just kill it and get my reward and move on.
