The game isn't fair

1. All my team has Mk2. Against Two mk4 ,one Mk3 and two mk2... Isn't not big deal? It's happening all the time . We can't win
2. Weak players... Seriously guys... Just 100-400 dmg the last 2-3 players in a team... What the hell ? I can do 7000 dmg, but they can't do nothing

 

A lot of the issues you're mentioning here is already talked about. Much of the same goes for all infamy levels all the way up to the top. The matchmaker is the problem, as players looking to progress are looking at alternate ways to help gain resources. Dropping infamy is one of them.

1. That is a known problem
2. Everything seems pretty normal to me, as you had 3 Fixer's on the team. you did your job, and the fixer's did theirs. Everyone can do great if they are constantly healed, altough 132 and 430 seems like a bad score. Seems like a brag attempt instead of a issue/complaint to me.

You should try to play the fixer, they are the people who can turn the waves on the battlefield, judging them by endgame scoreboard isn't fair or right.

 

You had 3 fixers on your team. You shouldn't expect them to do much damage. They are meant to heal others and tank shots for near dead players. They only shoot when given the opportunity. It's not like a shooter or defender whose sole job is to rack up damage. That's why your teams damage suffered, you had 3 fixers

Edit: Didn't see guys post above mine, basically what he said.

 

You had 3 fixers on your team. They were probably busy healing you and using their one little weapon to shoot once in a while, it's a tough match for sure. It was your job to do damage and theirs to heal you. Tough match, but it happens.

The biggest problem is that, at your level, it's not common to find players who have learned to work as a team. I recommend finding your fleeting buddy and battling that way to be sure you have one player who plays well with you all the time.
