Self Sacrificing node contradicting itself

Functionally this notable directly opposes itself by reducing all reservation efficiency only to add back some for minions, it would make more sense to have the "reduces spirit reservation efficiency of all skills" specify non-minion and change the increased down to 20.
Instead of reading "20% reduced spirit reservation efficiency of skills" and "40% increased reservation efficiency of minion skills"
Have it read "20% reduced spirit reservation efficiency of non-minion skills" and "20% increased spirit reservation efficiency of minion skills"
Why make it calculate the negative and positive for the same one? Unnecessary and confusing.
