In regards to Urgot, a potential rework
How to make him more useful, without changing too much of who he is.
Passive: Advanced Zaun-Tech Targeting Array - Urgot's abilities and basic attacks lock onto enemies Urgot has attacked, granting enhanced vision of their location.
Q: Augmented Noxian Hunter = Toggle Ability (On) - Urgot's auto-attacks gain increased range and damage, but expend mana per auto-attack. = Toggle Ability (Off) - Urgot's auto-attacks restore a portion of his mana if he kills his target.
W: Terror Capacitor - Urgot shields himself and a nearby ally, and grants them a portion of his Armor and Magic Resist. Enemies who attack a shielded ally are slowed and have their attack-speed reduced.
E: Noxian Anti-Personnel Charge - Urgot tosses an explosive that bounces and then rolls to a designated location, exploding after a short duration or right after hitting an enemy champion, launching shrapnel out and dealing damage to nearby enemies and reducing their armor and magic resist. An enemy champion may suffocate the shrapnel if they are on top of the explosive when it activates, but take increased damage and armor/magic resist reduction as a result.
R: Hyper-Kinetic Missile Salvo Rush - Urgot stores charges of missiles that replenish over time or after getting a kill or an assist. When activated, Urgot briefly channels before firing a missile in a target direction, which continues until it hits a target, exploding and dealing damage to all enemies struck. Enemies that Urgot has locked onto with his passive can be targeted by the missiles, and said missiles become homing, avoiding all terrain until hitting the target. While channeling, Urgot may reactivate the ability again to fire more missiles for his attack (extending the channel), for as many missiles he has stored.
