I like being in a pre-made team because I like playing with friends. I know a lot of how to play the modes and the characters, but sadly putting it all into practice is another thing altogether. Because of my poor twitch skills, lack of situational awareness, ease of which I get overwhelmed and ease of which I panic I often fail in the execution of most of the things I am trying to do. Which is why I try to focus on the minions because at least they don’t kick my ass. Well, when people let me. 
So if you see me on a team don’t worry about me and focus on the rest of the team. Please let me preserve at least s sliver of my self-esteem. The rest of the team is probably much better than me and a greater threat and I just do the minion stuff so it’s probably okay to leave me alone.
