Scaling Mr vs Flat for junglers.
I'm fixing my Jax runes, I've always done well with him in jungle and used FLAT MR but now I'm looking at it, would it be more useful to get scaling MR? I'm in low ELO and a game can end quickly in 20 minutes but usually, it ends after 30 minutes when everyone is nearly 18. And it's mostly the mid/support who specializes in AP, with some AD champs having little AP ratios.
Would it be more useful getting Scaling MR? That way late game + Jax ult gives enough MR, I also take the Fearless Mastery.
Adding a pole for quick answers.
