I still dont understand why your friends just dont run it fixed? I mean it is soloable so doing it with two people (one a healer) should be way enough. And even if you are on different server I cant just believe that she/he does not know at least another person in the game on the same server. You are also able to get to 99 by only running the first few floors. It might take longer but since your friends want to open all chests anyway then this shouldnt be much of a problem.

Also the palace does not have rules that say that it should be played this and that way. If you go with randoms, just ask at the beginning how they want to run it. If most of them want to do it the fast way you could still ask if they can open at least the chests on the way to the door and if not, well you can either leave or run it with them and hope for some chests in the rooms you run through.

I am also kinda surprised that someone has a help/call macro? Normally I would use macros to explain something that takes some time to type so why have a macro for asking help? Maybe they did not notice that this macro felt like spam for the rest? So thats why the other person also later spammed his help request? As a sarcastic reminder of your friend doing the same?

And if they were two people, why did they need the help anyway? Other than going into a lure trap which still should be manageable with two people, there should be no monster that could not be killed by two characters. And if your friend went into a room and pulled everything..well thats one them I guess?

Really I dislike toxic player too but in this situation I just cant take the side of your friends. You also only know about it by word because you were not there yourself. Maybe there is more to it? Or they just took it the wrong way?
