Here's a suggested change for Decisive Strike since you want it to crit. Instead of having the spell do a base spell damage pluse 140% of total AD as the total damage, change the spell so that it just adds bonus physcial damage. Here's my suggested change for you:

Change Damage scaling to this:

Deals Bonus Physical damage: 40 / 60 / 80 / 100 / 120 (+0.5 per Bonus Attack Damage)

Garen can still crit, but only his auto-attack will benefit from it. This way, it makes way more since what u did does not add much to a late game Garen. What you have makes grabbing crit rather useless as the 90 base damage is not really high. What I did was allow the spell to add bonus damage (like Jax's empower) but still allow him to cric, which now actually scales with AD.

Grabbing more crit on Garen is still really useful for him, and he has better late game scaling. His early game will suffer a tiny bit, but it's not like his Decisive Strike was the reason he was a terror early game.
