Death From Above prevents the turn from ending after using your sniper rifle for the first action, if you killed someone while you're on higher elevation than the target. Lightning Hands can be extremely useful for conserving more useful abilities for both the Sniper and the rest of the squad. For a Gunslinger, Lightning Hands is far more useful than Deadeye could ever be, synergizing very well with most other Gunslinger Skills.
For a Sniper, Lightning Hands allows the sharpshooter to weaken or finish off a nearby enemy before sniping them, or another target altogether. Lightning Hands is a free pistol shot against anything within range, working well for both Snipers and Gunslingers. Deadeye uses up both action points, even when shooting from a weapon different from sniper rifle. It is more suited for a Sniper than a Gunslinger because of this. Deadeye scales up more potently from improved equipment than Lightning Hands, due to its damage boost. As such, this skill is not very reliable until the drop can be compensated, but it is very powerful otherwise. Deadeye's aim penalty is 25%, not a direct -25, meaning the penalty's significance differs per target. Deadeye trades in 25% of the sharpshooter's aim for a shot with 50% more base damage.
The exception to this, of course, is when the sharpshooter is together with the rest of the squad.
Return Fire is more useful for the sharpshooter itself than it is for the squad, helping finish off enemies close to the sharpshooter rather than close to the squad.
Return Fire allows the Sharpshooter to fire back with their pistol at an enemy that attacked them. Long Watch allows players to activate enemy pods during the enemy turn, when the Sharpshooter is not concealed but a phantom Ranger can see the enemies. As critical hits cannot be scored in overwatch outside of late game Specialists, this ability's use of squadsight has the penalties mitigated to some degree. Long Watch is more useful for supporting the squad than anything else. Long Watch allows reaction shots at targets in an ally's sight radius. 2.6 Advanced Warfare Synergies: Specialist Skills. 2.5 Advanced Warfare Synergies: Ranger Skills. 2.4 Advanced Warfare Synergies: Grenadier Skills. 2.2 Internal Synergies: Gunslinger Side.
