Boxing people in in RA...is this possible...how difficult?

I was in RA earlier with a total jerk of a monk who insisted that the four of us with no pets could box a warrior who would not stop running. We of course had no snare and insufficient range dmg (monk, monk, spirit spammer, some sort of ranger) to kill him before he would just heal himself.

He insisted if we formed a perfect "cross" formation around the running warrior, that he would be unable to move.

1. Is this even possibe with 4 people and 0 pets?
2. How difficult would this be to do on a moving target?

Note: the map we were on did not have a lot of inhibiting terrain

If he is Running in open area you cant stop his movement by "making a cross around him" lol

Well I'm glad to see you say that because that monk was being a real jerkface to me and the other teammates.

Meet Random Arenas :\ Thats normal attitude, atleast he didn't cuss you and insult your mother before leaving the match.

They only way to have any chance of blocking ihm in would be to get him up against a wall them surround him...
