Lando
Lando is one of the more underrated heroes in the game but can deal some serious damage. His primary weapon is the x-8 night sniper which is a pistol which gives you night vision when you scope in, which is incredibly good for maps like endor where enemies are hard to see. The damage and fire rate work together but the gun has very minimal recoil allowing you to keep firing your weapon while your aim stays in relatively the same spot. This works really well on heroes with your shock trap as you shock them and spam your gun into the enemies head. This can do about half of Darth Vader's health. His shock trap is very useful as well because it also sights enemies on your radar so you know where they are and allows you to stand up to a lightsaber hero with ease. His smoke is not really that useful but I would put it not on you but in front of you and use your night vision to scope through it. This stops enemies from locking onto you while thinking that you are in the smoke when you are behind it. His sharpshot ability is good against heroes for that final bit of damage or when your weapon is cooling down. This is also good with flanks against enemy soldiers because you can kill them all at once before they know your there. Try and combo this with smoke as they don't know your charging it through smoke, so they won't shotgun you or charge you. Use Lando with a mixture of rolls for effective dodging and keep at mid range.
