And LGD.int has been showing why to pick Luna and why not to pick her. What they do with great success is grouping up and playing 5 man dota with her since she is really strong with just her spells. However they also showed why not to pick her when they shut her down in lane so she didnt get any lvls or farm and she then became totally useless for the rest of the game. The other team will just get BKB's and she will hit like a wet noodle.
