"The Blessed One", is it bad translation?

I found "The Blessed One" in English translation of Suttas. Because in Buddhism blessing is not legit/proper word to use to anyone, especially Buddha need not to be blessed, is it loosely translated or in purpose? I didn't see any part of Sutta that one can be blessed or a meaning that blessing can be done so far. What should be proper translation of "The Blessed One" in Sutta if it is bad translation?
