What you are getting with the no bid Orehas is a guaranteed clear. You don’t pay, so you don’t get to bid (remember the high level guy gets no gold for doing the run). It does not mean you get to be lazy and have someone else do the work. You should be helping to better learn the fight and to get the run over faster. You want to AFK/bid then you should find a real bus and pay or run it yourself in a mm game.
What do you mean with “participate”? if he meant you help killing boss then thats bs and he should not ask for no bid, specialy for 1500, however, if he ask you to not be 100% afk and make him wait 15 seconds on every teleport, you cant complain about that, unless clicking to move is too tiresome for you ofc
