All the low levels on my team?

Games Halo 5: Guardians

First I’ll list the sr levels of everyone in my last warzone assault match.
In order on the carnage report.
Red (enemy team)
69,93,66,69,60,66,37,43,32,27,31,47**>TOTAL(sr640)**
Blue (my team)
42,76,107,29,12,42,11,8,9,38,6,15**>>TOTAL (sr385)**

This has been happening more and more since I broke sr 100.
Seeing half my team be under level 20, and the enemy teams lowest be over 30.

The 12 man parties doing the rounds stomping in Warzone may have more than just a little bit to do with this.
