Champion Stat Analysis (for Wukong)
Wukong is a Diver class champion, a subcategory of the Fighter class along with the Juggernaut class. There are currently 19 Divers in the game:

We will be comparing average stats to Wukong. For these reasons I chose to not use Diana and Elise, as they are AP and it might skew things. Also, some stats are not taken into account, such as mana for manaless champions, or Kled's Health (Skaarl makes it weird). Lastly, Wukong's stats are not being used, therefore accurately comparing his stats vs the average of the other Divers.
To avoid listing too many champion stats information, I will simply annotate any difference higher than 1% in Wukong's stats vs the average.
at level 1...
Pros: 2.43% more Mana Regen, 3.06% more Attack Damage.
Cons: 22.28% less Health Regen, 15.98% less Mana.
at level 18...
Pros: 5.23% more Mana Regen, 9.68% more Attack Damage
Cons: 2.16% less Health, 16.79% less Health Regen, 5.55% less Mana, 2.23% less Armor
I always knew Wukong had sustain issues, but I thought it was only because he didn't have built in sustain. It also doesn't help that his Health Regen is actually shitty. His mana is also frustrating, especially early game, and these numbers show that. Would it'd be too much to ask for this one tweak?...
Lv 1 Health Regen 6 > 7.5 (Divers average 7.71)
can really use some more sustainability in lane. Since I don't expect a rework to come around for another few years, this should be a great QoL change. It will not impact balance at all.
