Question about tanking and loot rolls

As for charging, like what is a reasonable amount to ask for say level 30, 40 etc? When it is 4am and nobody is on I could see people paying, but I feel like that we irk me if someone did. Like someone else said, when one newbie gets 4 upgrades and you walk out with some bat wings a 3s priced bracers in over an hour… So I can charge but idk how much, or I can ask to or just need on an occasional item to even things out if need be. I appreciate the advice because I really don’t want to ruin someone’s experience playing if they have been waiting around for 20 or 30 minutes to feel conned or ninja’d. Not my goal. I really prefer prot spec and tanking over questing. The challenge feels more rewarding with handle big pulls etc seamlessly.
