Pre LU13... i ALWAYS precast 3 reactives on my tank, Post LU13, i never cast a single reactive until AFTER the tank has their first taunt off. one of the little learning curve things i had to learn the hard way about the "new way" to play a templar...

One more thing to remember is the range of your buffs. If the tank goes out of range of your buffs then comes back into range dragging mobs, to the mobs it looks like you just cast all your buffs at the same time, and therefore adds significant hate. Makes it really difficult to taunt the mobs off of you.
i was always trying to figure out why sometimes i was getting agro on pulls! i hadnt cast anything... my tank is my hubby, so i watched him and he was doing the same thing (taunts etc), there was no rhyme or reason why it was happening! now i know! 
) thanks! same thing happened to the Illusionist we play with... and he was always razzin my hubby "nice taunt dumb [Removed for Content]" etc... now we know thanks!
