Everyone one has a valid point except those who think they got priority because they are in a party.

But even though you have valid points the current system is flawed hugely and your ideas will simply not work.

One of the biggest problems with caravan is BLM/THM, two of them can easily duo a caravan. Anytime I see two doing them I don't even bother taking out my weapon because I will be lucky to get 1 hit in there and 1 ws off during all the fights.

The activity point system wouldn't work for the reason above. Anyone not being a BLM/THM would simply be screwed because they won't be giving the chance to do anything.
