First, thank you for the impressive and well polished work on this project.

Right now we have no way to check if a spell is in range to change priorities since IsSpellInRange is not exposed in state.
target.distance doesn't provide a reliable value and target.in_range uses an hardcoded value.
State.IsUsable won't work since self.rangefilter is nil or false.

Could you expose LSR.IsSpellInRange in State?

Give me examples of usage.

Gonna throw in in_range or action.whatever.in_range and see what comes of it.

If an ability doesn't have an actual range, it's going to return true. Or if you don't have a target. Or if you have a non-attackable target.

So basically it returns false if you don't have an attackable target or you're out of range for the ability.

Sounds good thank you.
I'm using this to prioritize sub rogue blink abilities (shadowstrike, shadowstep) over melee stuns (cheap shot) for non-raid APL.
