Sorry for saying the detaunts were dumb at FF then? 
The main issue was that agro control became dumb for preds / sorcs ~ what's the point when one can dps all day knowing they detaunt per second 2-3x more hate than they're gaining. Also it was an obvious bug as Evade for rogues / bards were still only in the 6-10k range, while preds were mysteriously upwards of 650k.
Though I do agree a lot of taunts / detaunts need upgrading, I don't even bother with Evade, the only detaunts worth a [Removed for Content] are the hate position ones.
