I think it all gets a bit hazy when it comes to "what should I put points in?" - there will always be a debate over it.
I put 16 points into stamina and 4 into int on my troll shadowknight (feel free to flame). I like to group, so the group is likely to see the benefit. Disease Cloud (the big "taunt") costs 10 mana... it's ample for the task at hand, rarely oom unless its after extended (10 mins or more) chain pulling. I'd say the extra stamina has saved my bacon more than a few times.
The guide says to add 20 to INT. Dying as a troll SK needs to be stopped at all costs (EDIT: particularly during hell levels!), it's not always nice to FD when you think your group is doomed
