Attack him in what degree? People tend to hyperbole things in reaction to make it seem more than it really is. All we get was "I'm being crucified" It could've been a simple "why do you have ballad up" or "why the heck do you have ballad up". For all we know, it could've been the former. The problem is his reaction to it as well; Mind you, they even went further to why ballad was not needed and how it was hurting his dps, and most we got was.
And as a bard main, this is incredibly frustrating to me when you're trying to sing ballad to boost healer dps...when you specifically have another song that does just that without lowering your damage.So i tell the Bard maybe she should consider not telling people how to play there jobs. Please read Part 2.
I'm not reinforcing or even encouraging people to wrongfully kick or harass people that are (un)intentionally playing inefficently. Infact, I didn't even mention the former. The thing is, we have such a limited perspective but everyone seems convinced otherwise that there is nothing at fault with OP, or if he was even wrongfully kicked at all.
The fact he stopped talking and eventually got kicked leads me to believe that he did not pay any attention to the party or their suggestion (solicited or not) and still kept ballad up anyway throughout the fight.
My point is, everyone should have at least some degree of performance in a party. I'm not even asking for savage-tier dps, but to grasp a basic understanding of your class and abilties. If they don't, then people are either going to point it out, and what you do with that regardless of how it's presented is up to you. You could keep that healer in your party who just refuses to turn off cleric stance and still doesn't contribute to any dps, or vote kick them because it's becoming a burden to the party. You could have a warrior tank that repeatedly dies to every trash pull because he can't stay alive in deliverance.
