Ref: The deprecated animation method Alpha:SetChange has been removed. Use Alpha:SetFromAlpha and/or Alpha:SetToAlpha instead.

Not sure yet how we'll handle this downgrade. Example of an upgrade: mooreatv/wim-3@34392c8

Andrew: Set from / set to alpha have to be done with multiple alpha animations, or clever use of OnPlay / OnFinished.
Like a fade in you'd want to do

<Alpha order="1" duration="0" change="-1"/>
<Alpha order="2" duration="1" change="1"/>

You can set OnFinished to set the alpha, but you will need a RunNextFrame function to accomplish it for OnFinished. It is called just before the animation is complete, meaning any changes to alpha and stuff wont apply. OnPlay is called just before, so it doesnt have the same problem.
Some animations are super hard to replicate in pre-wod clients, especially without being able to set childKey it makes it super annoying to sync multiple animations together.

everything I've tried is possible to port though, just super time consuming.

The bug has been mitigated with b4f3382 but could use a rewrite to actually allow things to use alpha changes.
