LeBlanc got preety big nerf,some time ago, people don't ban her, becouse they think that she is bad now, they're wrong. Some people still max W and build Morello or something as 1st item. It's really bad and it don't work

There are 3 choices, it depend what u need. If u need more sustain, gunblade is great. Protobelt gives u cooldown reduction and great active, sometimes little dash can make huge diffirence. Last option is GLP, it's good when u have mana problems + better sustain, slow is helping preety often, but i like more little dash.
