Well most skills, like in any game, are going to be sub-optimal, therefore a lot of the time making them obsolete. The only reason to have blood rain and not something better would be because you're going for a unique build, you just like it, or flavor, which is great too. Or maybe I'm missing its secret, idk :p
The discussion that makes more sense is: What are Tier 1, 2 , 3.. etc skills? Since there's technically a use for everything.
And there would be a difference in tier placement depending on if Solo or in a team. Apotheosis like the guy said could be huge in solo.
Actually, I would like to see a tier list made for the fun of it. We should make one!
As a solo player I consider Apotheosis the number 1 tier 1 skill. This thread made me goggle when I read that someone considered it bad. You have to think, to some extent in combat, until you get a hold of it. After which, combat for pretty much any build that uses it becomes a specific formula. Use abilities xyz in a specific order and you win.
True, it has no use in the last fight, but that is only because in the last fight you have the effect of Apotheosis active anyhow. If you did not have that effect, it would be useful there as well.
