There is an op exploit which has yet to be balanced.
You can tell that an organized teeam is using this exploit by pressing the [ TAB ] key at the screen where you choose your ship prior to battle.
Until this exploit is fixed, I would suggest doing what I am starting to do. That being not to play matches where it's obvious the other team is using the TAC ship exploit, are organized and you are going to loose.
The problem with this exploit is that if you have 2-3 tac ships of high tier, and a combination of arti, desi and dreads, and specially if those people make up an organized team that has been fightng together, you cannot kill the tac ships and it will be almost impossible to kill any ship being healed by them.
So when choosing your ship, press the [ TAB ] key, check out what ships the opposing team is using. If you see they are a team, using 2-3 tac ships and your side does not, quit that game. It is far better to quit that game and play another and possibly win.
You make 2-3 times more EXP when you win, so you are able to level faster, get better ships faster, better mods, etc which helps you win more. The time it takes to play a match you know the other team is using the TAC SHIP EXPLOIT, so you know you are going to loose compared to the amount of time it takes to cancel and join a more fair fight you might win, will allow you to make far more EXP than you would sticking to loosing fights.
Until the devs fix the exploit and/or balance things correctly, and until they fix the random team generating problem and organized teams using TAC ship exploit I would suggest just simply cancelling out of any unfair match where you are certain to loose. Don't play teams that are using the TAC ship exploit, they are using you for EXP fodder. You will notice they always say good game when they win over and over, to encourage you to continue to be EXP fodder. Those people know if you stop playing those matches, they are screwed.
So instead of allowing Dreadnought to decide you are going to loose to be exp fodder for a team using an exploit to win, quit those fights and re-que for a more fair, more equatable fight.
Losing sucks, losing most of the time sucks worse, loosing all the time will cause you to abandon the game.
