Damage

Personally, it seems that Jayce gets too much free damage. These are some numbers i looked at to take away some of that free damage but allows Jayce to actually do more if itemized for damage.

To the Skies! To the Skies!

From
Physical Damage: 20 / 65 / 110 / 155 / 200 (+1.0 per bonus attack damage)
To
Physical Damage: 10 / 45 / 80 / 115 / 150 (+1.25 per bonus attack damage)

Shock Blast Shock Blast

From
Physical Damage: 60 / 115 / 170 / 225 / 280 (+1.2 per bonus attack damage)
To
Physical Damage: 30 / 85 / 140 / 195 / 250 (+1.5 per bonus attack damage)

Thundering Blow Thundering Blow

From
Magic Damage: 40 / 70 / 100 / 130 / 160 (+1.0 per bonus attack damage)
Max Health to Damage Ratio: 8 / 11 / 14 / 17 / 20 %
To
Magic Damage: 40 / 70 / 100 / 130 / 160 (+0.9 per bonus attack damage)
Max Health to Damage Ratio: 5 / 7.5 / 10 / 12.5 / 15 %

Now, based on a Doran Blade + 15 AD rune/mastery page start (even as a bruiser build), at level 3 vs a 690 hp target:

Accelerated Shock Blast: 126
Hyper Charge + Transform
To the Skies!: 45
Hyper Charge Autoattacks: 172
Hammer Transformation Proc: 20
Lightning Field: 100
Thundering Blow: 120
Total: 583/690 (84%)
Total vs 30 Armor/MR: 433/690 (63%)

If you miss an Acceleration Gate Acceleration Gate + Shock Blast Shock Blast then 9 times out of 10 it'll be because you aimed poorly due to the speed increase it gets. The rest of the damage falls into place with the 30% Slow from To the Skies! To the Skies! and thats not even including an Exhaust, Ignite, jungler gank, support CC, etc.

PS: These are primarily focused on the damage aspect of the abilities, the mana costs of some of Jayce's abilities should also be considered as they are (with the exception of To the Skies / Shock Blast) are under 50 at ALL ranks.

(If anyone remembers YorickSquare Yorick's release, you'll know where that topic is going, for anyone else, read below)

Mana -- More reasonable alternative?

Focusing on Jayce's mana costs, I could see: Lightning Field Lightning Field & Hyper Charge Hyper Charge

From
40 mana
To
40/45/50/55/60 mana

Thundering Blow Thundering Blow & Acceleration Gate Acceleration Gate

From
40 mana & 30 mana
To
30/40/50/60/70 mana & 25/35/45/55/65 mana

Transform: Mercury Cannon Transform: Mercury Cannon / Transform: Mercury Hammer Transform: Mercury Hammer

From
0 mana
To
10/20/30/40 mana
  • This one will probably get the most negativity, and you could probably just do this change, and leave the other ability's mana costs alone and have a big impact to his mana usage where people would have to be more mindful about when he switches forms instead of spamming it all day for the freebies it gives.
