Most of the time, the matchmaker works good.
Sometimes, you get thrown into a battle in progress - which is not entirely bad (may safe matchmaking time) …
… but other times, it is just silly (when the game is already almost over)
2 PvP match-makings threw me into 2 battles which the captain committed suicide.
. (BTW: Once, the captain told me he didn’t know he was the new captain after the old captain disconnected)
1 PvP battle was lost because the enemy did hold all 3 beacons and there were like 150 points left.
1 PvE battle was lost because I joined as Rank5-6 only a Rank10
2 PvP, I had 2-3 *exceptionally bad nullPointer* players in our team which just spawn to die or which didn’t play in the first place (disconnect).

I know, this can happen from time to time, but after 3-4 lost battles, you should be on the priority list for better games.
When I manufacture better ammo or use the ammo gifted daily and get thrown into a match where the captain dies 2 seconds after I spawn with 1/2 the team dead or assaulting the enemy team alone, you lose hope and get frustrated - which I hope is not the goal of this game 
Even worse, you are never able to get on top of the score list for a loyalty-voucher-quest when your team already got 900 points from capturing beacons 3 times.

So please - add a detection for these situations. Give the player a team where players actually use their engineers and commanders when nobody else uses them already when he lost so many games in a row.
I know it’s possible, just check how many times a player switches his ship selection to match the team’s demands on a currently not available ship role.
