So I know we have all at least once dropped something and someone else pick it up, use it, and die. It's irritating isn't it? That is why I think that if you accidentally drop something in Kit PvP it can not be picked up by another person for 10 seconds. We work hard sometimes at getting really good things on PvP and it is annoying when some other person that hasn't worked for anything get it and get to use it. This is just what I think cause I had an enchanted Diamond chest plate with protection 4 on it. It might not cost a lot for some people, but for me having to rebuy something cost literally twice as much. So I think that if you drop something it can't be picked up by another person for 10 seconds so that if you do drop it by accident you can get it back.
No support, no point adding it.. and trading would be a huge issue with this as it'll take 10 seconds to pick up the items..
