How do I snap taunt?

[Dioptase]

Mainly I want to know about a few tricks to help me pick up adds faster in some fights. Such as in Garuda extreme when I need to pick up Chirada and the plume currently I flash/skorn chirada and provoke/lob the plume for threat and when I get them together flash to solidify my threat. However this doesn't always work and dps pull threat which makes a problem. My next scenario is the adds in Titan extreme when they spawn I pull them the same way as in the Garuda fight but my threat isn't solid and dps always pulls off me or I'll only get solid threat on one and lose it on a other. So my question is how should I gain threat over adds mainly in the titan fight should I stand with the dps get aggro then run them west or stand west and lob till they come to me?
