If my Ranger is pulling, which doesnt happen too often, i use this:
/gsay Shhh, %t won't know what hit %o
: ; useability <stealth attack name>
: ; useability <high damage attack name>
%t - targets name
%o - him/her/its
So group would see "Shhh, Lord Androus won't know what hit him"
another useful line for breaking contact in group situations, to perform back attacks.
: ; toggleautoattack
