I'm not the OP, but I'm pretty sure you're missing the point.If grease is OP because it’s impactful and the wizard can use it so often then surely something more impactful than grease coupled with the fighter being able to use it all the time is even more OP, right?
Or is a prone effect only strong because it’s a Wizard doing it?
The Wizard can spend a single action to AoE prone people at range. In theory, this is between 1-3 times a day.
The Fighter spends an attack to prone a single creature within reach that is no more than 1 size larger than you using a skill check instead of your primary attack mode where the target has a choice of two better defenses. In theory this is at will.
