Finn
Finn was added in the last jedi dlc and can do a lot of damage. His primary weapon is a full auto rifle which does a lot of damage and has quite a long range. When firing it at long ranges you have to aim a tiny bit in front of where you opponent is running as it has some travel time. This gun up close melts enemies though as with the easy headshots, you can keep hitting hard hitting bullets with ease. His big deal ability really helps him and his team because it allows you can fire the gun with no cooldown for a certain amount of time, so if your gun is on cooldown, you can use this ability to get your weapon back instantly. This ability also gives your allies that ability and also extra health which helps you and your team tank some shots. The only downside to this is that you can't sprint while this is active, but if you are sniping or holding ground, it doesn't matter anyway. This is great for holding chokes and mowing down enemies as you can just keep firing. Surprisingly, this is also quite good against lightsaber wielders as although you can't sprint, you can roll. So instead of moving back and firing, you can hold your ground and use your extra health and no cooldown to win the fight. His other ability allows him and allies around him to go of the radar and get a speed boost. While in this phase, he pulls out a pistol which is great for medium range and great for headshots. Although I don't think its as powerful as his rifle, its great for regular soldiers and infantry, but on heroes, I would go for the rifle. His last ability allows him to gain aimbot for his rifle. This is amazing for low health, hard to hit heroes like Boba and amazing at killing regular soldiers as you can fire into a group of enemies without really aiming and getting kills. This doesn't work t long range unless you get a star card for it, but is amazing to use otherwise. Finn's health is alright but keep boosting it using big deal and you also keep the health gain from big deal a short time after it goes away.
