I would largely remain neutral to the idea until examples of what people would like to see were introduced. I would be interested to hear what people though would be acceptable and fun, if anything at all.
I do, however, think that it could be a bad idea if it inspired people to be too conservative. I prefer things that motivate people to get in there and kill each other. I think the game would be boring if the main place you saw others was while you were both running from the boundaries since you were both camping afraid you may take limb damage and go around limping the rest of the match. I am not saying that is what will happen if this idea were implemented, but I am trying to think of all the repercussions.
