If I could tweak one thing in the game It would undoubtedly be IE.

I would not hesitate to change this infamous Rng stat-stick

I feel the bonus crit damage is way too high and crit chance way too low, and would trade power here.

not sure exactly how much to tune it by but Id give it 40% crit chance, and have it increase the damage of crits by 25%

why? mainly because the high crit % items are all attack speed, and there are lots of crit champs that rely heavily on weaving in periodic autos rather than constantly chaining them which makes low crit chance more viable.

additionally imo, +50% damage to an already huge burst mechanic is a little over the top anyway.
