Correction on one of your points. Pressure wash makes the projectiles travel further, not faster. Might be a tool-tip issue if that’s what you’re seeing, but it has always said further for me. I prefer the other helix choice. I won’t be sniping or getting heals fast, but my heals will be stronger.
Alani is not OP. Having played against multiple Alani players I know she isn’t. People say she’s a tank, but that’s dead wrong. Outside of 1v1 fights, she’s super squishy. She is a force to be reckoned with when you add more character’s to her support. The times that I have played as Alani, I’ve always had an ally traveling with me. We were able to keep three players at bay. (But that was because their Kelvin was suicidal and I was able to keep him in front of our turret.)
And later on in this thread, you were talking about how she needs to be nerfed because you have 50ish kills and less than 10 deaths. That is not an arguing point. If so, then Mellka needs a hard nerf. My first 10 games with her were never less than 15 kills and never more than 2 deaths. Most of the time no deaths.
