What is your favorite ultimate ability for that class?

So, are we talking about using AI in online games here? I thought we were just comparing which one is better. In that case, I'm strongly against AI. It's completely unnecessary. It interferes with its useless skills. Often, you need to develop differently for each race of the opponent, which is much more convenient and better. This is if we're talking about practical application. I'm telling you: don't use it. At least, don't try to use it when playing against me.
