A few days ago i sent a gift of Ranged support to a guild member only to find out that she has to be level 50 to be able to accept it.
I submitted a support ticket about it and now received an answer that since gifts cant be cancelled they cant do anything about it.
If gifts cant be declined or reversed even by support there should be no option in the merchant to gift things purchased by star coins to players under level 50! At the very least there should be a warning!
