I'd say that people target who ever they can target when so few is out of town. Don't expect good fights while people are macroing.

I have, on the other hand seem some really good fights, where a few people went against a bigger group. It has happen that they recall or run later on, but I assume it is due to resource deficiency. No one wants to really die when they have a total of 5 fs scrolls.

EDIT:
On the other hand I do not think that most groups will try to overpower people by share number, but those who really enjoy ganking, and see it as a sport, wont.
