[1.7.2] Spellcraft/Body of stone cooldown order matters

[trungaczne]

If you turn on spellcraft before body of stone then Earthquake will have 16s cooldown. If you turn on body of stone before spellcraft it will have 13s cooldown.

I think this has to do with the rounding and I suppose this is already known but I'm wondering if there's a more streamlined way to handle this (like putting the two reduction percentage together before applying them?)
