To be fair when you wipe its not the fault of a singular player but a collective of them either not understanding their class well enough. To put out enough DPS or healing to meet the checks, or do not understand themselves how the fights work.
In truth raid pugging has always been a famous word for a fatherless woman, due to the fact if you want to clear in a reasonable amount of time. You have to pain stakingly go through logs for end bosses to ensure everyone has seen it, and make sure they know how to play their class and spec.
Otherwise it turns into a wipe fest chore that results in what i said above due to how blizzard designs the raids to be. With players having zero tolerance or patience at the first wipe. Thanks to the amount of time it takes to do an activity and the limited time spans most have. With the latter being having no patience at all and being elitist and egotistical in their approaches.
It’s always the players fault even when they go out of their way to try, at least that’s the response I always see in these type of threads.
Sorry OP, people always expect others to play like them and assume they’ll have an easy time as they did obtaining said above. Good luck in the long run.
