Here is the information on the new gift limit for Marvel: Avengers Alliance.
Player's gift queue for unclaimed gifts will have a max cap limit of 350 instead of 700.
Maximum daily gifts each player can send per friend is now 10 instead of unlimited.
To avoid any confusion, this is a per friend limit. If you have 50 friends, you would be able to send up to 10 gifts a day to each friend. So you would be able to send up to 500 gifts to all your friends.
