This case just showed that apparently it is not.

My assumption is that since it's all eventually based on RNG, attacking bonus probably increases the chances that attacks conducted while bonus is in effect, will succeed. Defending bonus probably means that opponent's attacks will not.
And again, this case just showed that I did start scoring like crazy - only after giving defensive bonus
