Finding folks you mesh with is difficult. You're lucky if you do. You shouldn't fault people for not showing up. It's a soft removal. You can still play with us, just can't rely on you for raid. Of all the people that left the static or were dropped, only 1 actually had an issue with it. He was removed because he was a bit much and he was grating on folk's nerves. Which segues into another thing. Try not to burn folks out. Constantly beating your head against a wall is not healthy. Take breaks. Kill easier things. It helps. Also talking to members openly helps. If someone feels something isn't right hash it out. See who can do what to help.
Also, be lucky. The static I'm in has had it's ups and downs. We've had bad eggs and have been half annihilated at one point. Luckily we gathered up, pulled through and chugged along.
