experience varies, imo give people space to learn. large pulling is more skill based then people think. And a fresh player today may not have all the needed role skills to pull that off. I tried large pulling a few times and was met with wipe after wipe. With no idea how how/why...
I know it is possible, but you need people to teach you how. I was taught healing through large pulls by my fc, who had a boss to boss pull style. They told me to be calm, and heal best I could, that if a wipe happens, it happens. Get up and try again, thing is not everyone has an fc that helps. Not everyone, gets or wants tips. It best to just go with the flow.
claiming a tank is only a tank if they large pull... is a bit E... midset. Not everyone is the same, or learns the same.
