Probably.

compatible with sfo?

I could - but the Small & Medium mods are really to correct what I saw as a small imbalance of the game.

The hp/s regen number is a static number that doesn't scale based on unit size.
The amount healed (limit) is a number that *does* scale. 75% seemed too low so I increased it to 100%, but 100% feels good to me.

The BIG version is for people that just want to go BIG. :)

After using the Small version for a long while I've moved to the Medium for my Ultra unit size games. I'd still use Small if I was on Large, which is what I used to play.

Is it possible to change the limit from 100% to 150% or something like that? Otherwise this is not quite different from the small buff. However, more options are always great and your works are awesome!
