Well meat I gotta say im not one to tell someone how to play the game as I know I really dont like it but Im at about 7-8 hrs a level for my 5 guys and I have been doing the collection quests. Honestly Once you start to get used to them they arnt that bad. Few tips I picked up

1. I have my main pick up Maxnumber -1 so that my main comp will always beable to see the sparkles.
2. if two things are close together split up the team have member 2 and 3 go get them @ the same time rather then having 2 get both. only saves like a couple seconds but its a nice bonus to have guy 2 done and guy 3 only needs like 3 more items or so.
3. SPACE OUT listen to music and just relax its not a race. (I have to keep telling myself this)

One thing im really looking forward to is doing this again with my lvl 70 pally but only having to do all this crap once! I am seriously happy about that!
