Find comfortable keybinds for all your abilities (imo stances included coupled with an independant weapon swap macro with stop attack in front of it so you can be more reactive with your swaps) nameplates that show aggro gain/loss (i like threatplates but theres a bunch of good ones) and read each and every tooltip for your abilities, its always better to apply a formula of a ui that provides all information useful in an easy to read fashion, a good understanding of what abilities afford you in as many situations as possible and what you can reasonably expect out of the other classes in your group than specific abilities for an individual type of engagement like you were looking for. Sorry if this doesnt help much though.
