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.
Exterminate can be really mean if furia has the stun duration boosted almost killing non frontline champions with the damage dealt during the stun alone. getting Resilience will shorten this stun Giving you the chance to excape.
