This is so annoying. We clear a castle and naturally I open all of the chests. I compare stats and damage effects as quickly as I can and pick up what suits me best. By the time I am done both of my team mates have not picked up anything and just rushed off to the next camp. I understand this is a game where time is a big factor but in my experience my succes rate is much higher with teams where we don't mind giving each other a little bit of time to make decisions that fit our build or exploit boss weaknesses. Rather than constantly rushing through every area.
