My feedback would be to say that the game should look at the highest dungeon you are queued in the instance matcher then if no matches happen within a predetermined time period a parcel is delivered to the player with corresponding enchantment materials (and possibly a bit of gold/faded coins).
Example A:
1. A new player queues for Macellarius Catacombs
2. The timer reaches 15 minutes in the instance matcher
3. A parcel is then delivered to the new player containing 5 faded coins and 1 Frost Flower Weapon Crate
Example B:
1. A player queues for Fusion Laboratory
2. The timer reaches 15 minutes in the instance matcher
3. A parcel is then delivered containing 5 faded coins 1 Frost Flower Weapon Crate and 1 Stamina Seal
Example C:
1. A new character in Tera queues for Bastion of Lok (level 20)
2. The timer reaches 15 minutes in the instance matcher
3. A parcel is then delivered to the new character containing 1 item that automatically raises the character's level by 1 and 5 faded coins
I feel Tera players should be rewarded for spending time in Tera waiting for games when they could simply go play something else that is more active. The amount of wasted time without reward is currently enormous. Thank you for reading my feedback.
