its the first KQ peeps come across that demands everyone stick to their roles. the DDs HVE to stay back, the clerics HAVE to heal only and the fighters HAVE to be upfront taking the agro. its a steep learning curve but it has to be done!
after Mara no-one should be confussed as to their set roles in any goup/KQ and you learn really quickly to not pull accidently when running around.
of course there are some very stupid people out there who'll never learn.
re. why clerics didnt res. sick of resing morons? (nothing quite as irritating to clerics as mad peeps doing stupid stuff then saying you're not healing quick enough) just as likely skill recharge, resurect has a really loooong recharge time so not necessarily malicious
