I run solo on pvp a lot...join after a game is started & we're already behind...down by 2000 points with mere minutes to go...like your example, I jump over a wall for a FOH, take out 3 with their lead in the group...didn't watch score because we're so far behind...my teammates (randoms) do their thing & we win by like 100 points at the end...can't give up....that victory felt good...that's what PVP is....and I've lost big leads just the same way
