What is it with some players!

Angers me to no end.

As hard as it is to now find a fireteam it angers me so much when you do join one and the first instance someone dies or we die as a team and have to start at check point they leave.

Seriously!! Are some players just unable to have patience and determination to finish something they started.

Been playing 10 months and the last 2 has been awful even joining a fireteam let alone staying as a team throughout the content.

Just had to vent and get this of my chest.
