Taunt from your secondary is superior in the fact that it doesn't need to make a tohit check (in PvE) whereas the pool version does. I'm not sure if the duration is any longer or not.

Tanker secondary is superior in duration, flawless accuracy in PVE and with those bonuses you can easily afford to have range/recharge slots which do add more flexibility.
The flawless accuracy is the best thing tho. The "Sorry my taunt missed" is a [censored] excuse 
If tanking Arachnos AVs I'd feel safer with a scrapper tanking with confront XD because then I'll know the duration will meet the recharge.
Taunt isn't always necessary in a given team or for a given concept. Taunt only adds flexibility in shaping the battlefield and saving people mainly. Presence pool fear powers have proven very good for many a tanker offering active defense.
He will honor his words; he will definitely carry out his actions. What he promises he will fulfill. He does not care about his bodily self, putting his life and death aside to come forward for another's troubled besiegement. He does not boast about his ability, or shamelessly extol his own virtues. - Sima Qian.
Thx for the advice guys, never had a tanker very high so new to the whole taunt concept 
Hey All,
Quick question. I would like to get the taunt from the presence pool power so i can go on to get the fear power. However i would like to know if the taunt from my secondary is better/worse or equal to the presence taunt and if so should i get challenge or provoke? Thx
