People need to realise we were all newbies and going through the duty finder means getting newbies and shouldnt be speed running, find a party for that!
I take my time if its my first dungeon so I can get the lay-out, with so much going on its hard to get your bearings.
I had tank run off to mob then run off to grab more and come back, overwhelmed healer, tank kept dying. I had to stop being DPS to help heal, which shouldnt happen. Tank ranting and healer was upset saying he was new and didnt know what was happening. No one should feel that way.
When I started mine dungeon, I didnt know not to attack blob, everyone calling me names. Told them its my first mmorpg ever, first in dungeon. One said sorry and helped, others kept shouting.
Go find party to speedrun, dont act high and mighty because your lvl 60, there may be somone only lvl 19. Im lvl 35 only started dungeons as I like to do other things than main story.
Everyone was new once, be nice.
