Naughty Dog I hope you read this if not then other players out there should know what I am about to say is true and if you don't take heed of this.
Your team selection in Multiplayer is broken. The teams always end up stacked and trying to win against a stacked team is horrendously difficult. Trying to win against a team where one person is 13+ and everyone else is below 3 is tough for the low level players.
Games where one person is 13+ against a team of 0, 1's and 2's will end up with a 0 - 15+ every single time.
I realize that you must allow friends to play together but if the level difference between the two teams is so great then you should at least give the lower leveled team a buff or a boost of some sort in order to level out game play!
In these types of games all I see are team mates leaving and getting a hit to their population and those that are left can not get any supplies in order to keep their population healthy. I had a population of 55 before joining a game with a rank 13 who was owning everyone and not being killed, people just left the game and I gained almost no supplies to keep my population alive and on top of that I was on a mission where I lost 60% of my population because of this!
Your multiplayer is seriously broken and needs fixing ASAP.
Sounds like the level 13 guy knows his way around the map, knows how to be sneaky, and knows how to work with his teammates.
You do know the game was out for only like a few days... It kinda makes sense that the majority of the players will be really really low level with only a select few who burned their whole weekend on leveling being 10+
and as already mentioned, Level really means nothing as it doesn't go towards your unlocks, thats what the clan thing is. Besides with the exception of like 4 games, all my matches have been pretty even. Sure it kinda had one guy going all COD rushing gun em' down style practically losing it for his team from time to time, but this game relies more on your teamwork than a single players skill.
The best part of the multiplayer.
Did Steven buy this game or it's just too skillful for his taste?
Lol MP is broken because you're saying it's hard to win against teams that party up together. That's not a game being broken that's every MP game in the world. Obviously teams that party up and use teamwork always do better. You should try it yourself but you should always make the best of you're situation. I always try and motivate and help my team. I have a mic and I always talk to them whether they can hear me or not. If you gain alot of peoples trust during a match like reviving them or help them or being informative on the mic alot of times the same game or the next game they will cooperate more and you will be more successful against a party.
I have never partied up in all my time playing TLoU and I've done just fine. You'll improve, god knows when I first started playing I lost match, after match, after match. Now, I usually only lose to full teams, or if my team really is completley incompetant (all scattered through out the map, don't revive, etc)
Keep at it, the MP is faaaar from broken my friend.
