Interesting ideas, but having an ult that broke out of how helix choices work now (Only level 10 modifies your ult) might be a bit much.
Also having “It’s dangerous to go alone” a toggle would add a skill, or require another skill to be removed. It also would make the zelda reference pointless. 
But you aren’t wrong, theorycrafting is fun. I headed up a heavily modded CSS server, I did all the coding and the balancing for it. It was a really fun experience and I never had any complaints of the classes being imbalanced. I’m not saying I’m particularly good at it, all games are different, and how I balanced things was generally just trying something and seeing how it felt, then tweaking it over and over until it felt right. It’s part of why I’m leery of sitting on the sidelines and making suggestions. Without being able to actively feel each change you can’t know for certain what it might actually do to the balance of the system.
