I figured I'd take this opportunity to post some quick personal thoughts on how I see our game design in league of legends evolving. In response to Akshan, the general consensus has went from "Look at all these unique tools Akshan has, how can he possibly not be OP/overloaded and exist in the same game as Udyr/Annie?" to "Wait, this champion is REALLY weak and his W is holding him back". And this evolution in thought is interesting because it really speaks to how much there is left to learn about power budgets in League of Legends.
Champions can win in a variety of ways in League of Legends. Some of them are super obvious, stat-stick style win-conditions (a-la Jax or Jinx) where they just have big numbers that add up to winning fights heads-up. Inversely, though, some champions have power budget shifted into less obvious win conditions, like Bard's super unique utility/roaming power or Ivern's contributions to utility for his team (like buff sharing and low-econ jungling). Understanding that we can essentially tune down "traditional" power (in the form of stats) to introduce ways to win that are unique (like Akshan revive/roam power budget), keeps the game fresh as far as alternative playstyles and game-to-game variance.
To turn this into a thought exercise using numbers, if Zed or Lucian get 50 "win-rate points" from just their damage, target access, and other fighting power, that is perfectly okay as long as we understand that their utility will amount to essentially 0. Inversely, Akshan, for example, may get 10 "win-rate points" from his W utility alone, so we pull that power directly from "traditional" combat power sources, and tell the Akshan player to get creative with how they win the game and use the power budget allocated towards the W to create wins.
With this context, it comes at 0 surprise that players are struggling on release. They have been given a champion that's power is under budgeted towards combat compared to what they're used to, so they have to learn to win with his unique playstyle/win conditions. As we create more champions in league of legends, the exercise of trying to put power into kits that aren't just "more damage on X ability/combo" to diversify gameplay is one we will likely improve on over time.
If anyone has any questions regarding Akshan (I am the lead analyst on him), I'd be happy to answer.
