I've found you're either on a team full of 60's, or a team full of 20 and unders, and you're either steamrolling or the one getting steam rolled. Sort of a bummer to me, anyone else having this problem? Why don't they just split the teams? 

Ok

i've been having a problem with them splitting my party up it happens almost every time when we have 2 or more people its kinda a bummer

Matchmaking is a huge problem. Teams never really randomize, so you get a bunch of awesome players who want to keep a high K/D (and never leave) on one side and a bunch of newbie players or people who ragequit (due to how much their team sucks) on the other side. Whenever you join a game that's already in progress, expect to be on the latter team.
 
At first I wanted the challenge, but after the fifth time in a row of getting steamrolled in five minutes, it gets frustrating.

Level means nothing except time spent with the game. 
 
I understand the concern, but it is still a little unfounded. I've played with plenty of people at lower levels who completely understand the concept of the game.
