Maeve is a very good champ but you need to buy the right items: Haven or Blast Shield, Kill to Heal, Chronos, Cauterize are the best items. Only pick Wrecker if the enemy has a Torvald!
Flank/Damage pip is not as vulnerable as other builds use more caution when approaching him he has high burst damage and a heal. if your going to flank him try to wait till he shootsthe catalyst on someone else to give your self an edge.
