Mordekaiser "Rework"
By rework, I mean new Mace of Spades (Q). Sure it is thematically sound to the champion, but not to the champion's kit (especially noting that he is an immobile melee mage, which is fine being slow but powerful). Having an ability that requires an immobile melee mage to get in melee range to use it does not make sense because he will never be in range to use the spell almost never, just a spell to waveclear or kill monsters- things that don't run away, unless you are Mr.Crab. I won't post any other ideas because his kit is pretty solid and does not require any changes. Since Mordekaiser is pretty simple and easy, let's make this ability a little bit more difficult to use (a skill shot) to make the spell more rewarding for the player and add an element of counter play to allow the enemy to dodge the spell, increased isolated damage will remain.
Mace of Spades (Q): Cooldown: 8/7/6/5/4 seconds; Cost: 25/32/39/46/53 Health; Range: 800 units Mordekaiser slams a chained mace at the target location to deal 80/110/140/170/200(+60%AP)(+80%bonus AD) magic damage to struck enemies. If an enemy is isolated this ability deals 65% increased damage.
Base damage is identical, while I increased the AP ratio and decreased the Bonus AD ratio. Isolation damage is same as Karthus' skittles where in his case the skittles deal 100% increased damage if they hit only one enemy, this is 65% increased damage if the mace hits only one enemy. So this is a direct buff to Mordekaiser's Q but in a healthy way and grants a reward system for landing the ability. The spell is a buff since it scales better damage-wise with items, but he can use it more often since it is not restricted to his basic attack; while it is a healthy buff because it is now a skill shot and hence can be dodged and allow for a counter play element to the spell- so everyone wins!.
Hope you appreciate the idea and have a nice day! ^.^ ~ Stacona
