About group

when I grouped with someone , i almost cant loot any item...

I dont no why....and now i avoid to group....lol

Any one can answer me how can I change the loot seting?

This one is simple. The person who is the lowest level always gets more items thn the person who is doing all the killing. This is because the harder area YOU fight in the more xp and trophies gained. So basically your friend has either got rt and you haven't or else you are fighting with him while he is a lower lvl. Hope this helps atall

It is definitely NOT based only on level.

There is some luck to it as well.
