I've noticed that magicians can not summon directly into inventory unless s/he has the person in there group/Raid or trade with them, But what I think would be a pretty cool idea is if you put a little acceptance box like how Rez/Guild invitation works.. You can solve the random Summoning of items, and you will not have to group with them and You will know who summoned them.
I don't know just a small suggestion.
