PUG level range

I guess this belongs to Suggestions but I am hoping it might actually get an answer if posted here...
When PUGging the event, I am 70% of the time put in a map with 3 people with level close to mine, and a warrior that is about 4-6 levels above me. Often I am lv21 and there is a lv27 warrior, obviously undergeared.

Often the only way to win is to keep trying & dying until he gives up and leaves, at which point the others reset the boss and start again.

Could this PLEASE PLEASE be fixed for the next event? A party of lv21-24 is hard enough.
