I loved very much the quest and i would like to have it for everyone, i mean, more quests to advanced players and beginning players.
This one was perfect to learn how to move, attack and last hit, also how to buy and combine items but you forgot to tell the player how to use
courier so they dont get to go everytime to shop to buy their items =]

Also besides the beginners quest, you could make hard daily quests that earns shop items or something else to the completing players.

Nice job!
(and sorry my english)
