Maybe text errors, maybe bugs?
Primal Avatar ability Chill of Winter claims it effects "nearby allies" when it seems that it really only effects you. Not sure if bug or text copied from the previous seasonal themed abilities in the tree.
Fatesinger ability Grandeur provides an "Aura of Grandeur" that appears to only effect you. Auras generally refer to things that affect near by friendlies or enemies, bug or poor naming?
